What is Network Address Translation (NAT)?

The number of internet users is multiplying than any person in the world can ever imagine. In fact, it’s almost doubling itself every year. The number of users is more than the US population of more than three hundred million. Hosts are ranging to about a hundred million every year. This extreme growth necessitates unique codes to the computers of different users. It is the internet protocol. NAT is responsible for this. It gives the public IP of a computer.

Most probably you have come across the term IP address. Network Address Translation gives a router the ability to work as an agent, reading the private networks and configures it to a public address. The entire process is as to why every code is unique.

NAT Is a significant process where the firewall gives your computer a public address. It also assigns to a group of computers. Your device should be under a private network. Most firms take this for both security and economic uses. NAT assigns a unique site address to you.

Network Address Translation plays a vital role when communicating with computers outside your private network. Most times, organizations own their sizeable private network. Some of them are configured with a range with 192.168.255.255, 10.255.255.255, 10.0.0.0, to 172.31.255.255 among others. NAT works outside the servers that interconnect the printers or the file servers in an organization. Private networks IP address vary with the public one since it’s the role of the NAT, which in most cases is not in private servers. NAT allows you to access information from outside your network. In fact, as you are doing your research on the internet now, it’s the public IP address that allows you to do so.

How does NAT work?

The process occurs when the firewall recognizes a request from the computers with an internal IP. The machines here may be connected to a private network in a workstation. The internet requests that rely on the NAT are complex tasks. The end user cannot recognize the functions since they occur at high speed.

The request from the firewall triggers the firewall to make a further request to the internet using its public address. It is now the role of the firewall to get the information from the resource online and return it to the computer user in your workstation. As the end user, you think that you are communicating directly to the website you obtaining information. The website, on the other hand, is sending requested data to the firewall. When NAT chips into the network of computers in a workstation appear to have a similar IP address. One public address represents all the computers in the private network. In such case thousand users, represents one public address.

Modern firewalls store crucial information. It keeps all the data about the packet orders and most important the IP addresses of the computers. Besides, it gives information about the ports. In short, they are vital in helping about the nature of the connection. After the process of communication between the firewall and the workstation and the website ends, it removes all the data about the previous connection.

What are the uses of NAT?

In huge networks, it serves as the web server. Mostly it requires internet to access information from such servers. In such a private system, every computer in the server should have a robust firewall that guarantees safety from outsiders at the same ease at which network engineers can effectively route the network internally. NAT serves the function of providing firewall security. It puts stringent control for both sides of the firewall.
