Anyone running websites on a dedicated server deals with DNS in order to make their websites point to that server.
There are two basic ways this is done:
DNS stands for Domain Name System. Simply put, DNS is a worldwide database identifying domains and the Internet Protocol (IP) address of the server on which they are hosted.
Every computer connected to the internet (even your own home computer) has an IP address. For example, the IP address of the machine hosting interworx.com is 220.127.116.11. There are two types of IP addresses: static and dynamic.
