Some users have been enquiring about information on how to change WAN IP on Comcast, but they don’t understand what this message from Comcast means. Let’s dig into what this message means to Comcast.

3 Easy Ways to Change WAN IP on Comcast?

Wondering how to change WAN IP on Comcast? For Comcast cable internet users, their IP addresses usually stay constant for years. According to technical support, the IP is dynamic, but we found it as static. You can also find your Comcast IP address to check.

For Comcast users who need to change their WAN IP, here are three easy and convenient ways to get the job done:

1. Power Cycle

Comcast technical support recommends that you power cycle your modem/router. According to the tech support, using power cycling will change the IP address of the modem/router.

To do this, follow the mentioned steps:

  1. The first step is to turn off both the router and the Comcast modem.
  2. Wait about 20 seconds to 2 minutes after turning off the power. It’s up to you.
  3. Turn on Comcast after 20 seconds or 2 minutes and wait for a minute.
  4. When you turn on the router, the IP address will be changed.

However, power cycling is useful for a limited user base. Because some users find out that their IP address is the same after they check it after going through power cycling.

If this method doesn’t work for you, you can change WAN IP on Comcast using the next method.

2. MAC Address

If the power cycling modem/router doesn’t get the job done for you, jump on this method to change WAN IP address on Comcast. It is pertinent to mention that this method requires changing the MAC address. It can interfere with the settings of your router/modem.

Follow the steps mentioned below:

  1. In the first step, log in to the router and head over to the MAC address section.
  2. Now, go to the WAN MAC address tab.
  3. Change the last digit of the MAC address, but don’t change other data.
  4. After modifying the MAC address, power cycle your router.
  5. Now wait for two minutes and turn on the Comcast modem.
  6. After your modem is switched on, turn on the router as well and let it boot.

After going through these steps, your IP will be changed. You can also reset the modem after changing the last number of MAC addresses. Personally, we prefer the reset and power cycling.

3. Bridge Mode

If you see that your IP has not changed, there’s a possibility that your modem does not support this method. In simpler terms, if your modem has a built-in router, you need to bypass it.

For this purpose, Bridge mode is the best option but you will need to use Bridge Mode on multiple devices.

In case the problem doesn’t get resolved and the message persists, please contact Comcast Technical Support. The tech support at Comcast will help you identify your network and Comcast modem, and also change your WAN IP.


Yes, you can say that WAN IP addresses are public IP addresses or global IP addresses. This allows your computer to access the Internet over a Wide Area Network.

The router’s Wide Area Network (WAN) IP address is the address you get from your Internet Service Provider (ISP). You can find the WAN IP address of your router on the router’s configuration setup page.

To access your Comcast router remotely, you will need to start by connecting to your local network and accessing 10.0. 0.1 from the browser. Once you are logged in, go to Advanced > Remote Management.


In this article, we have explained three different methods to change WAN IP on Comcast. If you are looking to change your Comcast’s WAN IP, you can opt for any method that works for you. In case, no method works out, you can always reach the technical support of Comcast and they will eventually do it for you.
