What are DNS Lookup Tools?

DNS lookup tools, also known as DNS checkers, are tools for web administrators to monitor and troubleshoot internet issues. These tools help to identify domain name server records, such as an IP address that is associated with a given domain name. DNS lookup can also be used to perform a reverse lookup, which uses an IP address to find the corresponding website. Many DNS lookup tools are available online and offer both real-time and historical data for each request. These research-grade services provide detailed reports about the status of a particular domain or website and help facilitate the process of identifying potential problems with network connectivity. Compare and read user reviews of the best DNS Lookup tools currently available using the table below. This list is updated regularly.
