In this blog i will discuss Network Address Translation how it work and why we needed.
In IPv4 we have approximately 4 billions IP address but we also have 7 billions people leaving in the planet and also each of 7 billion people may want to use multiple devices to access the internet.So we have problem in our hand.
There are two way to overcome to this problem either Implement Network Address Translation or Implement IP6.
How Network Address Translation work with example
Home computer have also IP Address but instead one of those 4 billions public ip address they get private ip address assigned by router which is not accessible by the internet.
These IP Address are Reserved for Private Network
