10.1.1.1 is a private IPV4 address. It belongs to the block of private addresses within Class A (this block spans from 10.0.0.0 to 10.255.255.2555).
10.1.1.1 is one of the addresses used by router and modem manufacturers as a default gateway. There is no rule when it comes to default gateways and manufacturers can assign any private IP address to their products but some addresses are definitely more popular than others. Manufacturers usually choose addresses that are easy to remember and 10.1.1.1 is one of those.
The most popular manufacturers using this address as a default gateway for some of their products are Belkin (F5D5630au4, BoB), D-Link (DSL-502T, DSL-604T, DVA-G3670B, DVG-2001S), Sagem, and Siemens.
If your router’s default gateway is 10.1.1.1, you can use it to access router’s setup page and adjust/change different network-related settings.
If 10.1.1.1 is not your default gateway and if it is one of the available addresses in DHCP pool, it can be assigned (automatically or manually) to any of your devices connected to your home wireless network.
10.1.1.1 – Router’s Default Gateway
If you are using some Belkin or D-Link router, there’s a chance that your default gateway is 10.1.1.1. If you are not sure what’s the default gateway you can use ‘’ipconfig’’ command (Windows users), ‘’netstat -r’’ command (Linux users), or ‘’netstat -rn’’ command (Mac OS users). Once you confirm that 10.1.1.1 is, in fact, your router’s default gateway, you can type it in your browser and enter router’s configuration page. Before entering this page, you will have to type in router’s username and password in order to log in. Once you open configuration page, you can change your wi-fi network name and password, change router’s username and password (you might want to write down the new username and password somewhere), change security settings (encryption), make reservations in DHCP pool, etc.
10.1.1.1 – Dynamic or Static IP address
If it’s not your default gateway and if it’s one of the addresses inside the DHCP pool of available IP addresses, 10.1.1.1 can be assigned to your PC, phone, or any other device connected to your wi-fi network. It can be assigned automatically (as a dynamic IP address) or manually (as a static IP). If you want to assign it manually, you should check if it’s available (if it’s not already assigned automatically to some other device). If it’s already assigned to some computer, phone, or tablet, and you try to assign it manually to some other device, you will cause an IP conflict and both of your devices using the same IP address will be disconnected. In order to connect them again, you will have to resolve this conflict.
