Linux: create your own Domain Name Server (DNS)
One vital step to hosting your own domain is to set up a domain name server. One nice solution is to use Linux and the Berkeley Internet Name Domain (BIND) software. The primary job of a domain name server is to allow you and your users to associate your domains and subdomains with IP addresses. Oddly enough, even though the software is called BIND the daemon that you run is called named.
Generally speaking, you will need to have two servers (or at least two ip addresses) to act as nameservers. One will be the master nameserver where you set up all your settings and make all your changes and one will be the slave that will act as redundancy and will gather information from the master. Once you have set up your two name servers correctly you would associate them as your domain’s nameservers with the domain registrar (example: GoDaddy) that you used to register the domain.
