Who Am I? Ip? DNS? Domain Name?

What is an IP address?

Every device connected to the public Internet is assigned a unique number known as an Internet Protocol (IP) address.

to find out what is your IP address, visit http://whatismyipaddress.com/ for example.
Many other sites and services will show you that info.
If you are using FF, there is a great add-on that can displays your current IP address.

Every time you visit a website, you are interacting with the largest distributed database in the world.
This massive database is collectively known as the DNS, or the Domain Name System.
Without it, the Internet as we know it would be unable to function.

A domain name is the information that you enter into a web browser in order to reach a specific website. When you input a URL like www.example.com into a web browser, its domain name is example.com
So, a domain name is the human-friendly version of an IP address = easy to remember!

The DNS's job, then, is to take domain names and translate them into the IP addresses that allow machines to communicate with one another.
