Mar 25, 2024 · Developed by Cisco, Network Address Translation is used by a device (firewall, router, or computer that sits between an internal network and the rest of the world). NAT has many forms and can work in several ways: In static NAT, the computer with the IP address of 192.168.32.10 will always translate to 213.18.123.110.

- NAT only affects a little bit of your internet speed. It is barely noticeable if you’re using a reasonable router for translating your IPs.

Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. [ 1 ] The technique was originally used to bypass the need to assign a new address to every host when a network was moved, or ...
Network address translation (NAT)is a technique commonly used by internet service providers (ISPs) and organizations to enable multiple devices to share a single public IP address. By using NAT, devices on a private network can communicate with devices on a public network without the need for each device to have its own unique IP address.

In the case of regular users like us, NAT is a job handled by your router. The router has an IP address assigned to it by your service provider. That’s the address that the rest of the internet sees. Every device on your home network is assigned a private IP address, which is what they’ll use to talk to each other. When a device on your network wan...
Before we get into the types of NAT you’ll encounter, it’s a good idea to quickly discuss private and public IP addresses. By convention, certain ranges of IP addresses are reserved for specific purposes. Public IP addresses are reserved for the internet-facing devices such as your router or web servers. Your ISP allocates a public IP address to yo...
While the basic idea of what NAT is isn’t too complicated, in practice there’s a lot of nuance to how it actually works. There are various types of NAT that are appropriate for different translation needs.
To muddle things even more, some companies have decided to slap their own NAT classifications on things. This is mostly applicable to game consoles and you’ll find that when you do a network test, it will tell you that you’re using something like NAT Type 2 or NAT Type D. These classifications are specific to the console or device makers and you sh...
Most of the time, for most people, NAT works perfectly and with complete transparency. Sometimes however, it malfunctions or gets in the way. Once again, game consoles are most likely to run into issues, because some of their services need your network to accept access requests to your public IP address from outside, since standard NAT configuratio...
That’s all you need to know about what NAT is to get you started. The real nuts and bolts of how NAT works can get complicated quickly, but as long as you understand what NAT does at a high level and why it sometimes goes wrong, you’ll also understand why certain fixes work or won’t when you run into network issues.
NAT stands for network address translation. It’s a way to map multiple private addresses inside a local network to a public IP address before transferring the information onto the internet. Organizations that want multiple devices to employ a single IP address use NAT, as do most home routers. If you’re connecting from your home right now ...
A NAT works by selecting gateways that sit between two local networks: the internal network, and the outside network. Systems on the inside network are typically assigned IP addresses that cannot be routed to external networks (e.g., networks in the 10.0.0.0/8 block). A few externally valid IP addresses are assigned to the gateway.
