Internet, Networking, & Security Home Networking How to Work With the 10.1.1.1 IP Address Some routers use this default range for home networks By Bradley Mitchell Writer An MIT graduate who brings years of technical experience to articles on SEO, computers, and wireless networking. our editorial process LinkedIn Bradley Mitchell Updated November 25, 2019 Home Networking The Wireless Connection Routers & Firewalls Network Hubs ISP Broadband Ethernet Installing & Upgrading Wi-Fi & Wireless Tweet Share Email 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. Also, some home broadband routers, including Belkin and D-Link models, have their default IP address set to 10.1.1.1. Lifewire / Marina Li When the 10.1.1.1 IP Address is Used This IP address is only needed to either block or access a device that has 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. 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 they would 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. You'll need the admin password for the router, which is different than the password used to access the wireless network. 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. Client computers do not get better performance or improved security using the 10.1.1.1 address and range compared to other private address. 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 does work as the IP address for phones, tablets, desktops, printers, and other devices that exist within a home or business network. Problems Related to 10.1.1.1 Networks start addressing from 10.0.0.1, the very first number in this range. However, people can easily mistype or confuse 10.0.0.1, 10.1.10.1, 10.0.1.1, and 10.1.1.1. The wrong IP address adversely affects static IP address assignment and DNS settings. To avoid IP address conflicts, this address must be assigned to only one device per private network. The 10.1.1.1 address should not be assigned to a client if this IP address is assigned to the router. Similarly, administrators should avoid using 10.1.1.1 as a static IP address when the address is within the DHCP address range for the router.
