What is Network Address Translation?

Network address translation is designed to be used in the conservation of IP addresses. If you are working under strict or unavailable resources, you might be required to work with a limited address space. The limitation means that you will be forced to come up with means of networking your small network without relying on any other additional resources. Being resource means that you make your private IP network use a single IP address which is visible to the rest of the world. A single IP address means that the constraint of having a limited address space will not be reason enough to deter you from networking your devices and keeping your private network connected to the internet.

Security is effected more easily whenever you are using network address translation. This is due to the fact that your entire network is hidden behind a single address. This offers you the double functions of address conservation and security which is typical for remote-access environments. NAT allows for one device, typically a router, to act as the agent between the internet and the local network. As such, only a single IP address will be required to represent the entire group of computers to anything that is outside the network. In order to set up traditional network address translation, you will be required to make at least one interface on the router and a set of rules that will be used to translate the IP addresses on the payloads. This is important to ensure that your destination devices get the traffic that is intended for them.

Separating the incoming traffic to accommodate the computers and devices that are on the private network is important and gives you an advantage when it comes to managing your network. For instance, it lets you hide the payloads and make the headers routable. You will be able to route all the traffic that comes into the network on the basis of the IP address and routing information that you have designed and set up for the network. Your network can even be designed to route the internal packages independently. This makes it much easier to manage and you will not have to worry about the packages reaching their destination. All you will be left to deal with is how the packages from the network are able to reach the internet and in an intact format.

Networking is a useful skill to have and when you are able to set up networks, your computer hobbies become more fun and interesting. You will be able to build your own local networks and work with limited resources to create functional networks that appear as a single computer to the internet. Routing packages to the correct destination will also be made much simpler and you will be able to accomplish much more in this way. Take the time to learn about computer networking and sharpen your skill with practical exercises. With network address translation, you get to preserve address space and use the available resources properly.
