Domain Name System (DNS) is a hierarchical, decentralized database that stores the names of Internet resources. DNS supports a variety of application-level protocols, such as the Domain Name System Security Extensions (DNSSEC), to provide security and trust for DNS resources.
To verify the DNS domain, you can use the nslookup tool in the command line or the DNS lookup utility in a web browser. For example, to look up the DNS domain for google.com, you can use the following command:
nslookup google.com
If the domain name is correct, you will see a response similar to the following:
; <<>> DiG 9.10.
3-P1 <<>> nslookup google.com.
