10.0.0.1 Router Login & Admin Guide

10.0.0.1 is the default gateway on Xfinity (Comcast) gateways in the United States and on a number of Apple AirPort, Cisco and business routers. Because it belongs to the large 10.0.0.0/8 private range, it is also popular with network administrators for office networks and VPNs.

How to log in to 10.0.0.1

1. Connect to the router over Wi-Fi or with an Ethernet cable. You cannot reach 10.0.0.1 from mobile data or another network, because it is a private IP address.
2. Open a browser and type http://10.0.0.1 into the address bar, not the search box. If you search for it instead, you will land on a search results page.
3. Enter the admin username and password. Check the sticker on the router first; most routers made in the last few years have a unique password printed there. Otherwise try the defaults below.
4. Change the admin password straight away and check for a firmware update.

Default 10.0.0.1 usernames and passwords

These are typical factory defaults. They vary by model, firmware and ISP, so the label on your device always takes priority.

10.0.0.1 not working? Try this

1. Make sure 10.0.0.1 is actually your gateway. Your router may use a different address. Find it:
   • Windows: run ipconfig and read Default Gateway.
   • macOS: run route -n get default | grep gateway, or open System Settings → Network → Details → TCP/IP.
   • Linux: run ip route | grep default.
   • iPhone / Android: open the Wi-Fi network's details and look for Router or Gateway.
2. Use http://, not https://, unless your router specifically supports HTTPS. Some browsers auto-upgrade; type the full address.
3. Check for typos. Common mistakes include 10.0.0.l, 10.0.0.0.1, 10.1.1.1. An IP address contains only digits and dots.
4. Disconnect from your VPN, which can route local addresses away from your network.
5. Try another browser or a private window, or clear the browser cache.
6. Restart the router and wait two minutes before trying again.
7. Xfinity gateways in bridge mode stop serving the admin page at 10.0.0.1. Turn bridge mode off from the Xfinity app, or factory-reset the gateway.
8. On corporate networks 10.0.0.1 is often a firewall or core router you are not meant to manage. Ask your IT department before changing anything.

What you can change in the admin page

• Wi-Fi name (SSID) and password: use WPA3 or WPA2-AES with a long passphrase.
• Port forwarding: open ports for game servers, cameras or a NAS, then confirm with our open port checker.
• DHCP and reserved addresses: give printers and servers a fixed local IP.
• DNS servers: switch to a faster or filtering resolver.
• Firmware updates, parental controls, guest Wi-Fi and IPv6 settings (check the result with our IPv6 test).

About the 10.0.0.0/24 network

10.0.0.1 sits in the private network 10.0.0.0/24, which is reserved by RFC 1918 and never routed on the internet. Devices on this network typically receive addresses from the same range via DHCP. See the full breakdown in our subnet calculator. Your router translates these private addresses into one public IP, which you can see on our What Is My IP page.

Secure your router

• Change the default admin password and the Wi-Fi password.
• Turn off WPS and remote (WAN) administration unless you need them.
• Keep firmware up to date, and replace routers that no longer receive updates.
• Review the connected-device list regularly; unknown devices can be identified with our MAC address lookup.

Frequently asked questions

Is 10.0.0.1 my public IP address?

No. 10.0.0.1 is a private address used only inside your home or office network. Thousands of other networks use the same address internally without conflict.

Why does 10.0.0.1 ask for a password I never set?

That is the factory admin password, usually printed on the router's label. If someone changed it and nobody remembers it, a factory reset restores the default.

Can someone access 10.0.0.1 from the internet?

Not unless remote administration is enabled. Keep it disabled and use a strong admin password.
