A Domain Name System (DNS) server is a vital part of the internet infrastructure. It translates human-readable domain names, such as “www.example.com”, into numerical IP addresses that computers can understand. Without DNS servers, we would have to memorize the IP addresses of every website we wanted to visit, which would be very difficult and time-consuming.
There are a few different ways to check a DNS server. One way is to use the “nslookup” command. This command is available on most operating systems, and it can be used to query a DNS server for the IP address of a specific domain name. Another way to check a DNS server is to use a website like DNS Checker. This website allows you to enter a domain name and see which DNS servers are being used to resolve that name.
