Comcast Xfinity gateways use it by default, so it's the admin page for millions of US homes.
Addresses starting with 10. belong to the largest private range, 10.0.0.0/8, which companies and VPNs use as well as home routers. If your Mac's address starts with 10.0.0. and you're on Xfinity, 10.0.0.1 is the gateway's admin page; on a company network, the same address could belong to a corporate router you shouldn't log in to.

On a Mac
To open your router's admin page from a Mac, first confirm its address: System Settings › Network › Wi-Fi › Details › TCP/IP › Router, or run route -n get default | grep gateway in Terminal. Then type http://ADDRESS into Safari's address bar. The username and password are usually printed on a sticker on the router. On Xfinity gateways, the Xfinity app also manages most settings.
Frequently asked questions
What is 10.0.0.1?
A private IP address many routers use, notably Comcast Xfinity gateways. It opens the gateway's admin page from inside your home network.
What is the Xfinity router login?
Open http://10.0.0.1 while connected to your Xfinity network. The default username is usually admin; the password is on the gateway's label unless you changed it.
Why does 10.0.0.1 not load?
You might be on another network or your router uses a different address. Check the Router field in your Mac's TCP/IP settings.
