First, you must make sure no one else has the name you want. Then, you must register your new name with a domain name registration service. There are several companies on the internet that you can do this with, the largest is Network Solutions. If you want Vance.Net to host your site, and you want to register the name yourself, you will need to input Vance.Net's DNS settings in the form. Vance.Net can also register the domain name for you at a small charge in addition to the fee from Network Solutions.
To link your domain name to a web page, you must notify the site's host (i.e. Vance.Net) of the domain and the site you want it pointed to. Your ftp server settings would normally change after this, and your site host will probably charge a monthly fee. If you want to use Vance.Net to host your own domain name site, check our About Vance.Net page for pricing.
