What is NAT? Explain how NAT actually works.

Network Address Translation is the full form of NAT. It is a technology that is commonly used for IP translation and mapping. It allows sharing internet access to home networkers. NAT implements the accessibility by using a device or software which allows the entire home network to share internet access.

NAT acts as interface between the private network (home users network) and the public network (internet). NAT is available between the internet and the home network. When a request is sent from a private network to the public network, a little conduit will be opened by the NAT device between the home computer and the destination computer. The response sent by public network system will be sent back to the client though NAT.
