nameserver

In this tutorial I will describe how to install and configure MyDNS and MyDNSConfig. MyDNS is a DNS server that uses a MySQL database as backend instead of configuration files like, for example, Bind or djbdns. The advantage is that MyDNS simply reads the records from the database, and it does not have to be restarted/reloaded when DNS records change or zones are created/edited/deleted. A secondary nameserver can be easily set up by installing a second instance of MyDNS that accesses the same database or, to be more redundant, uses the MySQL master / slave replication features to replicate the data to the secondary nameserver.

Sometimes, we are required to resolve our internal domains on a local nameserver and external (internet) domains on our ISP's nameserver. There are different solutions to this problem, but in this tutorial, we are going to solve it through configuring a combination of caching-nameserver and BIND 9.

Nameservers work behind the scenes to tell your browser where to look on the Internet to find the web server your domain is hosted on. It may sound complicated, but you don’t need any technical knowledge to follow this guide. There are, however, a few requirements. You will need to have a registered domain name, a web hosting account, and the nameserver settings provided by your web hosting company.
