What is my IP?

Most of us know what IP addresses are. However, this article is for the ones who don't know what an IP address is and what it does.

You can check out your IP address here: What's my IP address?



IP is an abbreviation for Internet Protocol. Protocols are a set of rules which govern how data flows on the network.

I'll keep this short and simple so that we don't discuss the whole darn networking domain.

An IP address is a numerical identifier for a computer(s) on a network. These addresses can be classified furthermore. However, prominently there are two: 

  1. IPv4 
  2. IPv6
An IPv4 address is 32 bits wide. It identifies your computer or device on the internet. These contain network and host bits. 

Example: 123.23.1.222

Here, 123.23 are called network bits, and 1.222 are called host bits. The network bit's are more to do with your ISP and providers and the host bit's are what usually identifies your devices. 

Why IPv6 when we had IPv4? 

The addresses started to run out. Thus we moved to IPv6.
Unlike IPv4, IPv6 addresses are 128 bit long. Regardless of the name, the function is the same. They are used to identify a computer. 

Example: 2001:0db8:85a3:0000:0000:8a2e:0370:7334

You can read more about both of these on the Wikipedia website. If you have any questions, post them in the comments.

It's easy to identify your IP address, you can Google what's my IP and you will find your IP address.
