What is a nameserver?
Nameservers match domain names to IP addresses. When a visitor attempts to find a website that your server hosts, their computer asks a nameserver for the IP address of the domain that they wish to view. The nameserver returns the IP address for your web server and directs the visitor to the correct page.
You must publish records for your domain names to nameservers so that visitors can reach those sites. These nameservers communicate with other nameservers to distribute the records of sites that your server hosts. The propagation period is the amount of time that it takes for a domain's DNS records to spread across the Internet.
We recommend that you do not start your nameservers unless you plan to use them.
