Domain Name Resources Domain name system (DNS) allows you to create DNS records for your domain, like A records, MX records, NS, and CNAME records, without needing your own name server. For a yearly fee you can use our name servers, which are updated hourly, to add and remove DNS records for your domain. DNS is a general purpose distributed, replicated, data query service. The principal use is the lookup of host IP addresses based on host names. The style of host names now used in the Internet is called "domain name", because they are the style of names used to look up anything in the DNS. Some important domains are: .COM (commercial), .EDU (educational), .NET (network operations), .GOV (US government), and .MIL (US military). Most countries also have a domain.
