Description

Domain Name Web Management System

The present invention relates to the management of domain names and IP addresses for providing Domain Name Service (DNS), wherein the administrator is directed to a managed host having IP version 4 (IPv4) and IPv6 (IP version 6) addresses. Easy domain management, remote management over the web, and system-based challenges that can arise when performing manual editing tasks, and can prepare for the upcoming IPv6 era. A domain name web management system.

In October 2002, the IETF, the International Internet Standards Organization, converted an international standard for multilingual domains by converting Korean domain queries into ASCII (English, numeric,-) in Internet-enabled programs (browser, e-mail, etc.) and forwarding them to a name server. Decided.

Users can use applications that reflect these standards, or install separate plug-ins (programs that perform conversion) on their PCs.

Name server, mail server, and web server administrators should set the ASCII converted string as host name.

In order for a standard to be reflected in the program, the application developer must develop and deploy an application that reflects the standard. It is estimated that the time required for this will be about 2-4 years afterwards (LIFE standardization stage is three stages: Proposed Standard-> Draft Standard-> Internet Standard).

Until the standard is reflected, you can use Korean.KR by installing the plug-in program distributed by NIDA. The plug-in program supports only certain browsers based on Windows, so ftp, telnet, ping, nslookup, etc. Does not support

The international standard for multilingual domains was decided to accommodate multilingual domain names by changing the application without changing the name server infrastructure. However, because most of the applications you're currently using don't support it yet, you need a separate assistive tool. This is the encoding plug-in, which is a short-term solution until the standard is applied to the application in a stable manner.

When the plug-in is installed, Hangul domains entered by Internet users are converted to ASCII strings consisting of English, numbers, and hyphens in the application on the user's computer, and then sent to the name server.

Under Windows IE 7.x, Hangul domain can be used by using separate plug-in among Hangul.KR support software. Hangul domain is not required in Internet Explorer 7 or higher version or Netscape Navigator 7.1 and Mozilla 1.4, Opera 7.2 or higher version without additional plug-in. Can be used.

Internet domain management systems are still in use today with the introduction of the Internet, and their importance will continue to be emphasized as IPv6 addresses are introduced.

Currently, when using Linux and Unix operating system as domain name server, there are many difficulties in operating domain name management system. In case of operating system of Linux and Unix, domain name host information is managed in file type called ZONE. Administrator adds or deletes domain name or host information manually and edits the zone file manually. As a result, the domain name server stops working, causing the organization to be paralyzed by preventing the organization from finding the domain names of the web servers, email servers, and various servers of the organization. This is the case even when operating in an IPv4 environment consisting of 32 bits (15 characters) that can be memorized. This is the case when managing domain names in the IPv6 era of 128 bits (39 characters) that cannot be memorized. Difficulties can only be increased. On the other hand, Microsoft's server operating system has an Active Directory-based domain name management system. However, it does not provide a web interface, which requires an administrator to visit and work with the computer when performing domain name management.

Korean Patent Laid-Open Publication No. 10-2003-65064 relates to a method for allocating IP addresses in a network based on TCP / IP, and more particularly, to a method for managing domain names for dynamically or relatively statically assigned IP addresses. It is about. Here, relatively static means that the same IP address is allocated two or more times by the DHCP routine.

Maintaining the pair information of the IP address-hardware unique number on the DHCP server side, and if the update is made, broadcasting the updated contents to the DNS server; Maintaining the pair information of the IP address-hardware unique number on the DHCP client side and, if there is an update, broadcasting the updated contents to the DNS server; And the DNS server side receives the pair information of the IP address-hardware unique number from the DHCP server side and the DHCP client side, adds it to the mapping entry if it is received from the DHCP server, and if so, receives the mapping entry from the DHCP client. A domain that enables domain name services for dynamically or relatively statically assigned IP addresses, including adding or updating, and allowing the DHCP server and DHCP client to broadcast the IP address-hardware unique number pair information to the DNS server. Although the name management method is described, in the case of a managed target host requiring a fixed address, it is managed through manual registration, but there is no mention thereof.

Korean Laid-Open Publication No. 10-2004-65643 discloses an IP address and domain name auto-registration method, which includes Duplicate Address Detection by multicasting a neighbor solicitation (NS) message including an IP address and a domain name of a host. Doing the process). As a result of performing the DAD, if a host using an IP address or domain name that is a duplicate of the host's IP address or domain name does not exist on the network, the IP address and domain name are automatically registered in a storage area of a DNS server or a plurality of other hosts. do. As a result, hosts in networks that follow the IPv Version 6 (IPv6) protocol can automatically store and manage each host's IPv6 address and domain name without duplicates, even when a DNS server is present and even when no DNS server is present. Although a method of automatically registering an IP address and a domain name is described, there is no mention of manual registration for a managed host that requires the fixed address mentioned above.

Publication No. 10-2006-41113 uses the question and answer information of the Domain Name System (DNS), which is forcibly stored in the Virtual Domain Name System (Virtual DNS) when the Internet address to be accessed cannot be accessed. A virtual domain name system capable of accessing an Internet address and a management method thereof, comprising: a domain server checker configured to check an operation of the domain server while making a query request for address information of the specific domain from a domain server; If it is determined by the server checker that the domain server does not operate, the virtual domain name system of the IPv4 / IPv6 terminal and the management method thereof include an address information allocator for allocating address information forcibly transmitted from the domain server. Is known, but manual or custom about domain name registration There is no explicit about how,

Publication No. 2006-0054661 discloses a communication method between an Internet Protocol version 6 (IPv6) network and an Internet Protocol version 4 (IPv4) network, including a dual stack transition mechanism (DSTM) client, a DSTM server, Establishing a TEP / DNSv4 domain name system (DNS) that is connected to an IPv4 network and performs V4 domain name processing; Sending, by a V4 host located in the IPv4 network, a DNS lookup request for the DSTM client to the DNSv4 server in the IPv4 network to the DNSv4 server; Obtaining, by the DNSv4 server, an IPv4 address of a DSTM client through communication with a TEP / DNSv4, and forwarding it to the V4 host; And an IPv4-IPv6 switching method using a dual stack switching mechanism, wherein the V4 host connects to the DSTM client using the obtained IPv4 address.

Publication No. 2002-0079271 describes the use of proxy, NAT, and DHCP technologies on an internal server with a different public IP address through the Internet on an external host that is dependent on an external server with a public IP address. A method of operating a host having a fixed domain forwarded to a private IP address for performing connection management to an internal host in a subordinate relationship that is in physical association with the internal server having a private IP address, the method comprising: (a) Setting a fixed domain having a public IP address of an internal server; (b) registering the fixed domain in a conversion table for forwarding the private domain to a private IP address granted from an internal server; (c) requesting an external server to look up a fixed domain name from an external server and accessing the public IP address of a corresponding internal server having the fixed domain; And (d) executing a reverse gateway that connects the information of the external host connected to the internal server to the internal host, wherein the host has a fixed domain forwarded to the private IP address. The operating method is open, but there are differences in managing reverse domain names using reverse domain names.

Publication No. 10-2004-0097849 discloses a method and system for automatically generating and registering a domain name and an IP address in an IPv6 (IP version 6) network, and receiving name information of a network to which a given host belongs. Making; Generating a link local address of the host and determining whether the generated link local address is already in use; Extracting, from the link local address, an interface ID used to distinguish the host if the determination result is not in use; Generating a domain name using the interface ID and the network name information; And it can be seen that the domain name auto-registration method characterized in that it comprises a step of registering the generated domain name to the domain name server, but in the case of a managed host that requires the above-mentioned fixed address, There is no mention of the method of manual registration.

Most of the conventional techniques are related to a method and system for automatically generating and registering a domain name and an IP address in a network. In the case of using a Linux and Unix operating system as a domain name server, the domain management system operates in a domain. The name and host information are managed in the file type called ZONE, and the administrator manually edits the zone file manually when adding / deleting / changing the domain name and host information, and the domain name server stops working due to incorrect data input. The organization's paralyzed state is caused by not being able to find the domain name of the web server, email server, and various servers of the server, and the administrator manually registers the managed host and the technical configuration that the administrator remotely manages on the web. Uncomfortable, IPv4 and the coming IPv6 era It is even a problem to be solved by the present invention to develop a web domain name management system that allows you to easily manage your domain name.

The present invention can be easily managed by the administrator for a managed host having IPv4 and IPv6 addresses requiring a domain name, remotely managed through the web, and may appear when performing a manual operation. It is a solution to the problem of the present invention to solve the various difficulties in the system level and to provide a domain name web management system that can be prepared in advance in the coming IPv6 era.

The present invention can be easily managed by the administrator, and can be managed remotely through the web, regardless of the place, and various difficulties that may occur when performing a manual operation (domain name server with incorrect data input) It stops working so that the organization's web servers, email servers, and other servers' domain names can't be found, resulting in systemic paralysis and domain name management that can be prepared in the upcoming IPv6 era. There is an advantage to preparing the system.

In order to achieve the above object, the present invention includes the steps of registering a domain name in a domain name server in order to register a domain name for an IPv4 host or an IPv6 host; Storing in a reverse domain table of a database for giving a reverse domain name to a host having an IPv4 address to which a domain name is assigned; It relates to a domain name web management system configured including storing in a reverse domain table of a database for giving a reverse domain name to a host having an IPv6 address to which a domain name is assigned.

According to the present invention, when a domain name manager is connected to a domain name web management system through an Internet connection, registers, uses, or changes information, the domain name information is stored in a database using logic, and then the domain name information registered by the administrator. When a non-specified Internet access general user requests the corresponding domain information, the domain name web management system provided by a DNS executor (domain name service execution program) will be described in more detail as follows.

In the present invention, in order to register a domain name for an IPv4 host or an IPv6 host, the domain name must be registered in advance in the domain name server as shown in the flowchart of FIG.

  1) An administrator first accesses a domain name web management system, which is the result of the present invention, using a web browser.

  2) The administrator clicks the Register New Domain Name button on the web page.

  3) The administrator inputs the following data in the screen. (Input items: domain name, administrator email, renewal cycle, retry cycle, release cycle, minimum value, TTL, reverse DNS use)

  4) After the input is completed, immediately after pressing the save button, check the validity of the input value. Domain Name Validity, Email Validity, Update Cycle Range, Retry Cycle Range, Release Cycle Range, Minimum Value Range, TTL Range.

  5) After the validity of the input value is confirmed, check whether the domain name with the same name is already registered through the database processing logic.

  6) If the domain name is not a registered domain name, create a domain name table, and automatically create and store SOA records and NS records there.

  7) If it is checked that the reverse DNS is used among the input items of the administrator, after creating the reverse domain table, the SOA record and the NS record are automatically generated as above and stored in the reverse domain table.

  8) After the storage is completed, the domain name server generates and stores the domain name server configuration file through the domain name list stored in the database in order to recognize and service it.

  9) After the name server configuration file is created, the registration process is completed by reloading the domain name server.

  3 illustrates a flowchart for assigning a domain name to a host having an IPv4 address.

 To assign a domain name to an IPv4 host, the domain must be registered in the domain name server in advance.

1) The administrator can select A record type, NS record type, MX record type, CNAME record type, and SPF record type when registering IPv4 host in the domain name web page. Here is an example of inputting an A record type. When the A record type is selected, the following input information is required. IPv4 address, host name, TTL value, and whether PTR record is used.

2) Check the validity of the value entered by the administrator. Hostname validity, IPv4 address validity, TTL value range, and so on.

3) Create a record for the A record in the domain management processing logic. In other words, if the domain name mydomain.com, host name myhost, IPv4 1.2.3.4, TTL 3600 (myhost.mydomain.com, A, 3600, 1.2.3.4), create a record.

4) The record thus created is stored in the domain table through the storage logic of the database processing logic.

5) The process checks whether PTR is used. If PTR is selected, a PTR record is created. That is, it is made in the following form. (4.3.2.1.in-addr.arpa, PTR, 3600, myhost.mydomain.com.)

6) The record thus created is stored in the reverse domain table through the storage logic of the database processing logic.

4 illustrates a flowchart for assigning a domain name to a host having an IPv6 address. To assign a domain name to an IPv6 host, the domain must be registered in the domain name server in advance.

1) The administrator can select the AAAA record type, NS record type, MX record type, CNAME record type, and SPF record type when registering an IPv6 host in the domain name web page. Here is an example of inputting an AAAA record type. When the AAAA record type is selected, the following input information is required. IPv6 address, host name, TTL value and whether PTR record is used.

2) Check the validity of the value entered by the administrator. Hostname validity, IPv6 address validity, TTL value range, and so on.

3) Create a record for the AAAA record in the domain management processing logic. I.e. domain name mydomain.com, host name myhost, IPv6 2001: 2b8: 3fff: 0: 1: 2: 3, TTL 3600 (myhost.mydomain.com, AAAA, 3600, 2001: 2b8: 3fff: 0: 1 : 2: 3) Create a record.

4) The record thus created is stored in the domain table through the storage logic of the database processing logic.

5) The process checks whether PTR is used. If PTR is selected, a PTR record is created. That is, it is made in the following form. (3.0.0.0.2.0.0.0.1.0.0.0.0.0.0.0.f.f.f.3.8.b.2.0.1.0.0.2.ip6.arpa, PTR, 3600, myhost.mydomain.com.).

6) The record thus created is stored in the reverse domain table through the storage logic of the database processing logic.

5 is a screen for registering a user domain name. The domain can be registered by inputting the screen of FIG. 5, and the following information is required to register a domain.

Registration item Contents User domain name The domain name you want to use. Manager email Email information of the user who manages the domain. SERIAL NUMBER The zone file version. Normally set the number of days the zone file was modified or created. Check this value on the primary name server and update the secondary name server information by transferring the zone file from the primary name server if it is greater than the serial number representing the copy of the secondary name server. REFRESH The time that the secondary name server periodically checks for updates to the primary name server. RETRY When the secondary name server tries to connect to the primary name server by the refresh value, it sets the time to reconnect if the primary name server fails to connect. EXPIRE How long the secondary name server will trust the information from the primary name server. If the secondary name server cannot connect to the primary name server, it trusts the primary name server information backed up before this value is exceeded. MINIMUM Same part as TTL TTL Specify how long a name server will hold the information after querying the domain and fetching it.

Fig. 6 is an A record (IPv4 domain name) registration screen;

The A record is a record that specifies the IP address of host_name. Add the host name and IP corresponding to the following record to use the subdomain.

The followings are required when adding A record.

Registration item Contents Hostname The subdomain name you want to use. TTL Specify how long a name server will hold the information after querying the domain and fetching it. Data Set the IP of the subdomain.

If no value is entered in the host name, IP for the root domain is set.

Multiple IP addresses can be assigned to a host. For example, if the A record is set to two IPs for the host www.test.com, the client will try to access www.test.com. The client then randomly connects two IP addresses. This setting is often used to reduce the load on Web sites with a large number of visitors.

FIG. 7 is an AAAA record (IPv6 domain name) registration screen. In the screen of FIG. 7, the AAAA record is a domain record for IPv6, and an IPv6 domain may be added in addition to AAAA.

  Extended IPv6 Support: AAAA Resource Record

  IPv6 Address: A Resource Record

AAAA RR: host A ddress RR (Resource Record)

In the case of an IPv6 address, it is expressed as 128 bits and has a different format from an IPv4 address. Resource record for IPv6 address is newly defined as AAAA RR.

AAAA RR: IPv6 Ad dress RR (Resource Record)

  AAAA RR reads "Quad-A RR".

It is known that the IPv6 address uses 128-bit address space, which is four times larger than the IPv4 address (32-bit), so it is known as 'AAAA'.

The following is required to add AAAA record.

Registration item Contents Hostname The subdomain name you want to use. TTL Specify how long a name server will hold the information after querying the domain and fetching it. Data Set the IP of the subdomain.

Below is an example of the A RR and AAAA RR formats of the IETF RFC document.

Name TTL CLASS TYPE DLENGTH RDATA www.test.co.kr 1800 IN A 4 192.168.0.1 www.test.co.kr 1800 IN AAAA 16 2001: 2b8: 5c0: 1: 0: 0: 0: 1

8 is a mail domain registration (MX Record) screen, in which a mail domain is registered;

MX records let you configure Mail Exchange.

Exchange mail for the address corresponding to host_name to another host,

In fact, this setting alone does not make Mail Exchange perfect, so the server that receives the mail must be the queuing server, and the mail recipient must be set at the final destination of the mail set by the MX record.

What you need to add MX records

Registration item Contents Hostname The subdomain name you want to use. TTL Specify how long a name server will hold the information after querying the domain and fetching it. Preference If multiple values exist, the smaller the value, the higher the priority.

To add a mail domain, you need an A record for one MX record and more than one MX record.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows the overall process of the domain name web management system of the present invention, wherein a domain name manager is connected to a domain name web management system through an Internet connection to register, use, or change domain name and host information. If you do this, the information is stored in a database using logic, and when an unspecified Internet user requests information about the domain name, the administrator provides the information entered by the administrator through the DNS launcher (Domain Name Service Execution Program). .
