While working with internet in home or at organization we know that we take internet connection and it works.

But inside that we don't know actually how it goes like we talk about organization perspective several users using the same internet connection at the same time.

Our ISP Internet Service Provider provides a single or public IP that is used to browse the internet.

When this connection gets shared into the organization we create private IP to the number of users sharing the same connection.

These IP can be assigned manually or can be assigned automatically using DHCP Dynamic Host Configuration Protocol.

When we use send any request it gets sent from our public IP and when we receive response it gets from the public IP and internally gets mapped to private IP using the NAT Network Address Translator.
