A domain name server (DNS server) works like a phone book for the Internet. It translates a domain name into the numeric IP address that computers use to find each other.

When someone opens www.example.com, their browser asks a DNS server for the address of that name and gets back an IP address such as 203.0.113.10, then connects to it. Every domain points to two or more nameservers, which hold its records. The nameservers you set at your registrar decide which provider answers for your domain: to use our hosting, set the nameservers from your welcome email.
