When the 10.1.1.1 IP Address is Used
This IP address is only needed to either block or access a device with this IP address assigned to it. For example, since some routers use 10.1.1.1 as the default IP address, access the router through this address to make router changes.

10.1.1.1 is a private IP address that can be assigned to any device on local networks configured to use this address range. Some home broadband routers, including Belkin and D-Link models, have their default IP address set to 10.1.1.1.

Routers that use a different default IP address can have their address changed to 10.1.1.1. Administrators might choose 10.1.1.1 if they find this address easier to remember than alternatives. However, even though 10.1.1.1 isn’t different from other addresses on home networks, others have proven much more popular, including 192.168.0.1 and 192.168.1.1.

How to Connect to a 10.1.1.1 Router
When a router uses the 10.1.1.1 IP address on a local network, any device within that network can access its console by opening the IP address much like any URL. Open a web browser and enter http://10.1.1.1/ in the address bar.

The page that opens at this address is the portal that accesses the router settings. You’ll be asked for the username and password.

The router default login credentials are included in the router documentation. The default login credentials for D-Link routers is usually admin or nothing at all. If you don’t have a D-Link router, use a blank password or use admin since most routers are configured that way out of the box.

Client Devices Can Use 10.1.1.1
Any computer can use 10.1.1.1 if the local network supports addresses in this range. For example, a subnet with a starting address of 10.1.1.0 would assign addresses in the range 10.1.1.1 to 10.1.1.254.

Use the ping utility to determine whether any device on the local network is actively using 10.1.1.1. The router console also displays the list of addresses the router assigned through DHCP, some of which may belong to devices that are currently offline.

10.1.1.1 is a private IPv4 network address, meaning that it cannot communicate directly with devices outside the network, such as websites. However, because 10.1.1.1 is used behind a router, it works as the IP address for phones, tablets, desktops, printers, and other devices within a home or business network.
