Name servers are the Internet's equivalent to a phone book. A name server maintains a directory of domain names and matching IP addresses. The information from all the name servers across the Internet is then gathered in the Central Registry. Host companies check in with the Central Registry on a regular schedule to get updated name server information, which makes it possible for people across the Internet to access your web site. When your domain is set up, information about your domain name is added to our name servers. That information is then sent from us to the Central Registry to be used by the other name servers on the Internet.
It usually takes about 48 hours before name servers on other networks will be able to access the information after the Central Registry gets it. This 48-hour period is referred to as propagation.
