How to Check NAT Type in Windows 11: A Step-by-Step Guide

Checking your NAT type on Windows 11 is a task that can be accomplished relatively quickly. By knowing your NAT type, you can understand better how your computer is connecting to the internet and whether it may be impacting your online gaming or other internet activities. Let’s dive into how you can check this on your computer.

Step by Step Tutorial on How to Check NAT Type on Windows 11

Before we get to the nitty-gritty, it’s important to know that checking your NAT type can help troubleshoot connectivity issues. It’ll give you a clearer picture of your network environment and how it might affect your online experience.

Step 1: Open Command Prompt

First, you need to open Command Prompt on your computer.

Once you have opened Command Prompt, you are ready to input commands that will help you check your NAT type. You can open Command Prompt by searching for it in the start menu or by typing "cmd" in the run dialog box (which you can open by pressing Windows key + R).

Step 2: Type in the Command

Next, type "netsh interface teredo show state" into the command prompt and press Enter.

This command will display the current state of your Teredo, a protocol that’s used to facilitate communication between IPv4 and IPv6 networks. It is especially relevant for checking your NAT type as it relates to gaming and other services that require P2P connections.

Step 3: Review the Information

The information that appears will contain your NAT type.

You will see details like the type of NAT your system is using (open, moderate, strict), the Teredo server name, and the client refresh interval. The NAT type is what you’re looking for, and it can affect how well you connect to other players online.

What Happens After You Check Your NAT Type

After you’ve checked your NAT type, you’ll have a better understanding of your network’s compatibility with various online services. If you find that you have a strict NAT type, for example, you might run into issues when trying to play games online or connect to specific services. Knowing your NAT type is the first step in diagnosing and potentially fixing these issues.

Tips for Checking NAT Type on Windows 11

  • Make sure you’re running Command Prompt as an administrator to ensure you have the necessary permissions.
  • If you receive an error message, double-check the command you’ve typed for any typos.
  • Understanding the different NAT types can help you identify whether you might have a problem: Open NAT is ideal, Moderate may cause some issues, and Strict is likely to cause problems.
  • If you’re trying to improve your NAT type, consider enabling UPnP (Universal Plug and Play) on your router.
  • Keep your network drivers up to date for the best performance and connectivity.
