DNS (Domain Name System) lookup is the process of finding the IP address of a domain name. When you enter a domain name into your web browser, your computer performs a DNS lookup to find the IP address of the domain, so it can connect to the correct server and load the website. Performing a DNS lookup involves sending a request to a DNS server, which looks up the IP address and returns it to your computer. DNS lookup is essential to how the internet works, as it allows computers to connect to websites using domain names rather than IP addresses.
To use a DNS lookup tool, you will need to enter the domain name that you want to look up, and the tool will return the IP address of the domain. Our free DNS lookup tools provide additional information, such as the DNS server to perform the lookup and the record type (e.g., A, MX, CNAME, etc.).
