Static DNS Explained

When a computer is connected to the internet with a static IP address, setting up the DNS for the domain is a relatively simple matter of adding an A record to the domain name's zone file. A zone file is just a special text file describing everything about a domain name, where to send email for the domain, and where the website is located for example. The A record is that section of a zone file that specifies the name and the IP address where the appropriate server is located. Here is an example of an A record:

www.example.com. IN A 192.168.1.2

Zone files are stored on a computer called a nameserver. A nameserver is a computer that is designated to answer all questions from other computers about specific domain names.
