Domain Name: When you create a website, you will have to give a name to it. Such as this particular site is called www.indiastudychannel.com. It is the identity of the "website" over the internet, and any user asking for it is redirected to this website. Every website has a unique name. The www represents that WORLD WIDE WEB, then comes the name of the site, and finally the .com for commercial or .org for organisation, representing the kind of website, or locality of it like .in for India and .uk for United Kingdom.
IP Address: Now, something different from the domain name, IP Adress is the identity of your computer over the internet network. They are ususally numbers sets like: 172.16.254.1. Every computer will have a unique IP address while using the web. This particular thing can be used by security sources to track you down in case you do something illegal over the internet.
