Hi

What is the meaning of DNS Lookup in GWT?

DNS query is a request for a website name or uniform resource locator (URL) that the domain name system (DNS) server responds to with the IP address from its zone file cache, if possible. If the server doesn’t have the IP address requested, it forwards the request on to another DNS server. Iterative DNS queries are also known as non-recursive DNS queries.

DNS (Domain Name System) is one of the most important technologies/services on the internet, as without it the Internet would be very difficult to use.

DNS provides a name to number (IP address) mapping or translation, allowing internet users to use, easy to remember names, and not numbers to access resources on a network and the Internet.

In computer networks, a reverse DNS lookup or reverse DNS resolution (rDNS) is the querying of the Domain Name System (DNS) to determine the domain name associated with an IP address – the reverse of the usual "forward" DNS lookup of an IP address from a domain name.

The process of finding out the IP address of any URL on the Internet is known as DNS lookup.
