A nameserver is part of DNS for a website translates domain names into the required Internet Protocol (IP) numbers so that people can find your site using a Web browser. An IP number is a unique, numeric identifier used to specify hosts and networks. Every domain name must have at least 2 nameservers. Check out the Wikipedia description of nameservers (new window).
Changing Your Nameservers
In order for your site to be found by typing in your domain name address you will need to tell your domain registrar (where you registered your domain) what server holds the information for your domain. This process is called changing nameservers. All you are doing is pointing your domain to our network of servers.
Once you have made the change with your registrar, it can take anywhere from 5 minutes to 72 hours (rarely longer) for this change to be distributed throughout the internet (we call this nameserver propagation).
24-7 Webs uses several different nameservers. Ideally you should be using our broadcast DNS nameservers. Check with support services to verify what nameservers you should be using.
Please feel free to contact our support services if you are unsure who your domain registrar is.
If you are having difficulty with this step, check your registrar’s help files.
