Xfinity (Comcast) Default IP Address List
Instructions to find your Xfinity (Comcast) router's IP address

Most Xfinity routers have a default IP address of 10.0.0.1.

The IP address is required when accessing the Xfinity router's web interface to configure it.
Since some of the models don't follow the standards, you'll have to check in the table below if the common default doesn't work.

You can also check the instructions on how to figure out your Xfinity router ip if you are connected to the router's network.

To access the web interface you'll also probably need a username and password, if you find your model in the list there's a link to the default settings for that model. Most Xfinity routers use the same default usernames and passwords so you can also check the Default Xfinity password list to try with that one.
