About Nameservers

Nameservers are essential components of the Domain Name System (DNS) that store and maintain DNS records for domains. They translate human-readable domain names into IP addresses that computers use to communicate. Each domain typically has multiple nameservers for redundancy and reliability.

When you look up a nameserver, you can see its IP addresses and a sample of the domains it manages. This helps understand the infrastructure supporting various domains.
