What is 10.0.0.1?
10.0.0.1 is a private address used by some gateways for their admin page. Open http://10.0.0.1 while connected and log in with the details on the device label or in the ISP's app. Check that your default gateway is 10.0.0.1 first; many devices use other addresses.
Some ISP-supplied gateways use it (Comcast Xfinity gateways in the US are a well-known example), as do some mesh Wi-Fi systems and business routers. It's part of the 10.0.0.0/8 block, the largest private range, which is also popular in offices and campuses.
Network details
With the usual home-network mask of 255.255.255.0, a router at 10.0.0.1 manages this range:
| Address type | Private (RFC 1918), not reachable from the internet |
|---|---|
| Network | 10.0.0.0/24 |
| Subnet mask | 255.255.255.0 |
| Device addresses | 10.0.0.1 – 10.0.0.254 (254 addresses) |
| Broadcast | 10.0.0.255 |
Some networks use a different mask. Your device's network details show the real one.
How to log in to 10.0.0.1
- Connect to the router by Wi-Fi or cable. Mobile data won't work.
- Confirm the router's address: it should match the default gateway in your network settings (how to check).
- Type
http://10.0.0.1in the browser's address bar, not the search box. - Sign in with the admin username and password from the router's label, or the ones you set.
- After logging in, change the admin password if it's still the one on the label.
Common typing mistakes
- 10.0.0.l
- 10.0.1 (a missing group)
- 10.0.0.0 (the network address, not a device)
If your router's internet address starts with 10
Look at the WAN or Internet status page in your router. If the internet-side address is 10.x.x.x (or 100.64–100.127.x.x), your ISP is placing you behind its own NAT. This is common on mobile broadband and some fixed-line services, and it means:
- Port forwarding on your router won't make anything reachable from the internet.
- Hosting game servers, remote camera access and some VPN setups won't work without a relay.
- Your public IP is shared with other customers.
Some ISPs offer a public or static IP on request, sometimes for a fee. Compare your router's WAN address with what What is my IP shows: if they differ, there's NAT upstream. Public vs private IP explains CGNAT in more detail.
A /8 range, but usually a /24 network
10.0.0.0/8 covers about 16.7 million addresses, but a home gateway at 10.0.0.1 almost always uses a 255.255.255.0 mask, so your devices get 10.0.0.2–10.0.0.254. If a device shows 10.0.1.x or a different mask, it's probably on another network (a mesh node in router mode, or a VPN). The subnet calculator shows exactly which addresses share a network.
If 10.0.0.1 doesn't open
- Wrong address. Check your default gateway; your router may use another address.
- Not connected to that router. Turn off mobile data and VPN apps, and connect to its Wi-Fi or cable.
- Browser upgraded to HTTPS. Type
http://explicitly, or try another browser. - Router frozen. Restart it: unplug for 30 seconds, wait 2 minutes.
- Still stuck? See the full router login troubleshooting and reset guide.
Questions
What is the username and password for 10.0.0.1?
There isn't one universal password. Most routers print their admin username and password on a label on the bottom or back, and many newer and ISP-supplied units have a unique password per device. If the password was changed and nobody knows it, a factory reset restores the label's details. Lists of "default passwords" online are often wrong for your exact model.
Is 10.0.0.1 a public IP address?
No. The whole 10.0.0.0/8 range is reserved for private networks and can't be reached from the internet.
Why do I get 10.x addresses on mobile data?
Mobile networks assign private addresses and share a smaller pool of public addresses among many users (carrier-grade NAT). It's normal; it just prevents incoming connections.
