DNS Lookup or Domain Name System Lookup lets you find the IP address of a specific domain name. It also reveals a lot of other details about the domain name. If you need to perform lookup often, I am sharing a few free DNS lookup tools & online services.

Windows has an inbuilt command line tool – nslookup. It can be used to diagnose the Domain Name System (DNS) infrastructure. It needs TCP/IP installed on your computer to work.
