If you’re wondering whether Verizon uses CGNAT (Carrier-Grade Network Address Translation) for your internet connection, you’re likely interested in how your home network interacts with the internet. CGNAT can affect various aspects of your online experience, such as gaming, port forwarding, and remote access to devices. Here’s a step-by-step guide on how you can check if Verizon is using CGNAT on your connection.
What is CGNAT?
Before diving into the steps, it’s essential to understand the basics. CGNAT is a technology that allows internet providers to share a single public IP address among multiple customers. This helps conserve the limited supply of public IPv4 addresses. However, it can create challenges if you want to use services that need a unique IP address, like hosting a game server or accessing your home network from outside.
Here’s how it works:
When you use your home internet, your router assigns private IP addresses to all your devices, like your phone or computer, and translates them into one public IP when connecting to the internet. With CGNAT, this process is repeated at the ISP level, allowing them to group several customers under the same public IP address. This conserves IP addresses but can cause challenges for certain online activities, like gaming or running a server, where a unique public IP might be needed.

Steps to Check if Verizon Uses CGNAT
1. Find Your Public IP Address
Start by finding out what your public IP address is. You can do this by visiting PureVPN’s feature “What is my IP” Write down the IP address that appears on the page.
2. Check Your Router’s IP Address
Next, log into your home router. This can typically be done by typing “192.168.1.1” or “192.168.0.1” into your web browser’s address bar, depending on the router. Once logged in, look for the WAN (Wide Area Network) section, where your router’s IP address is listed.
3. Compare the Two IP Addresses
Now, compare the public IP address you found on “What is my IP” with the WAN IP address from your router. If the two IP addresses are different, Verizon is likely using CGNAT on your connection. If they are the same, then you are assigned a public IP address directly, and CGNAT is not in use.
4. Contact Verizon for Confirmation
If you’re still uncertain after following the steps above, the best way to confirm is by contacting Verizon’s customer support. They can provide details about whether your connection is behind CGNAT and explain any implications it may have for your specific needs.
5. Third-Party Dynamic DNS Services
If you’re running a server and need a public IP for access, a Dynamic DNS (DDNS) service can help. DDNS services allow you to use a domain name that updates automatically with your current IP address, even if it’s behind CGNAT.
Steps:
- Sign up for a DDNS provider.
- Configure your router or devices to update the DDNS with your current private IP.
- Use the domain name provided by the DDNS service to access your home network.

How to Check if Verizon Uses CGNAT
To determine if your Verizon connection is under CGNAT, you can use any of the following methods:
Method 1: Check the Router’s WAN IP Address
- Open a web browser and enter your router’s IP address into the address bar.
- Enter your username and password to access the dashboard.
- Navigate to the status screen on the dashboard.
- Find the section labeled as ‘WAN IP’ or a similar term, which might vary based on the router model.
- Examine the IP address assigned to the router’s WAN interface.
- If this IP address falls within the range of 100.64.0.1 to 100.127.255.254, your connection is likely behind CGNAT. This IP range is designated for CGNAT usage.
Method 2: Compare WAN IP and Public IP Address
- Follow the steps from Method 1 to find and note down the WAN IP address from your router’s dashboard.
- Open a new tab in your web browser
- Search for “what is my IP address” and press Enter.
- Remember the public IP address displayed by the search results.
- If the WAN IP and the public IP address are different, it indicates that your ISP is using CGNAT.
- If they match, your connection likely has a direct public IP address, meaning it is not behind CGNAT.

Why CGNAT Matters
For most casual internet users, CGNAT won’t cause noticeable issues. However, for more advanced users, such as gamers or those who need remote access to their home devices, CGNAT can pose challenges. Knowing whether CGNAT is in use will help you better understand any network limitations you might face.
By following these steps, you can easily determine whether Verizon uses CGNAT on your connection and take action if needed.
Frequently Asked Questions:
What are the signs that I am on a CGNAT network?
Indicators of CGNAT include:
- Difficulty with port forwarding or connecting directly to certain services.
- Shared public IP address across multiple devices or users.
- Issues with specific applications that require unique IP addresses, such as online gaming, VPNs, or remote access.
Does CGNAT affect my internet speed or performance?
CGNAT itself does not directly slow down your internet speed. However, it can affect applications that need a unique IP address or open ports to function efficiently. Online gaming, remote desktop access, and some VPN connections may experience delays or connectivity issues on a CGNAT network.
Can I disable CGNAT on my Verizon connection?
Verizon typically does not allow users to disable CGNAT, as it is a network-level setting. However, some users can request a static public IP from Verizon (often for an additional fee). This static IP would bypass CGNAT and give you a unique IP address.
