What Is My Local IP

What Is The Role Of A Local IP Address?

In order to understand the role of a local IP address, let’s look at an example of internet browsing. 

Our home router assigns a unique IP address (commonly known as a local IP address) to every connected device.  When we look for some website:

1. The request goes to our home router, which has its own IP Address that has been assigned by the Internet Service Provider(ISP). 

2. Then, this request reaches the ISP Router, they have another IP which talks to the internet through a Public IP.

Once there is a response from the website, how does an ISP know where to return this request?

1. The ISP Router gives this request back to your home router, based on your Router IP, and then

2. Then, the home router provides the information to your device based on the local IP Address.
