The goal of PAT is to conserve IP addresses. Most home networks use PAT. In such a scenario, the Internet Service Provider assigns a single IP address to the home network's router. When Computer X logs on the Internet, the router assigns the client a port number, which is appended to the internal IP address. This, in effect, gives Computer X a unique address.

This type of NAT is also known as NAT Overload and is the typical form of NAT used in today’s networks. It is even supported by most consumer-grade routers. PAT allows you to support many hosts with only few public IP addresses. It works by creating dynamic NAT mapping, in which a global (public) IP address and a unique port number are selected.

Dynamic PAT is used any time multiple internal hosts need to share a single public IP address. On a small scale, this is exactly what your home Wi-Fi router does. You may have 5-25 unique devices on your home network, each of them with their own private IP address.

Techopedia Explains Port Address Translation (PAT) An example of PAT is a home network that is connected to the Internet. Within this setup, the system’s router is assigned a discrete IP address. Multiple users can access the Internet over the router, and are each assigned a port number as they do so. PAT is used to give internal network hosts access to external network hosts.

Port Address Translation (PAT) is a type of Dynamic NAT through which address translation can be configured at the port level, and the remaining IP address usage is also optimized. PAT maps multiple source local addresses and ports to a single global IP address and port from a pool of IP addresses that are routable on the destination network.

Instead of choosing the same IP address every time, this NAT goes through a pool of public IP addresses. This results in the router or NAT device getting a different address each time the router translates the local address to a public address. 3. PAT. PAT stands for port address translation.

If there’s no public IP address available, the router rejects new connections until you clear the NAT mappings. However, you have as many public IP addresses as hosts in your network, you won’t encounter this problem. NAT Overload, sometimes also called PAT, is probably the most used type of NAT. You can configure NAT overload in two ways, depending on how many public IP address you have available.

The idea is anyone can use these addresses, or even re-use these addresses, for as many hosts as they like on their internal network. NAT can then translate the multitude of hosts using Private addresses into a much smaller set of Public addresses – thereby curbing the rate of which IPv4 addresses are being utilized.

Early (pre 2008) home networks were predominately wired networks. Wired networks use Ethernet over UTP cable and tend to be faster than wireless networks, which is an important consideration if you are a gamer. The simple wired home network diagram below shows a minimum setup with a switch and broadband router.
