DOMIAN name identifies one or more ip address.for example teachnix.com represents about a dozen IP addresses. Domain names are used in url to identify particular web sites. For example, in the URL http://www.teachnix.com/index.html, the domain name is teachnix.com
Every domain name has a suffix that indicates which top level domain it belongs to. There are only a limited number of such domains. For example:
.com (use world wide level)
.co.in
.in (used in india)
.net
.biz
.name
.us ( used in unitied states
.pk (used in paskistan)
.edu (mostly used for education sites)
internet is based upon ip addresses not on domain names.every web server requires a domain name system to translate domain name system to ip address.first we have to buy web hosting.
