A Quick Overview of the Network IP 192.1.1

192.1.1 is a public network address

The network IP address 192.1.1 refers to the range of public IP addresses between and, but don't confuse it with the 192.168.1 network. In fact, many people mistakenly refer to as 192.1.1.

Home networks commonly use the to address range because many broadband routers are configured by default to use this private IP network range. Unlike 192.168.1, however, 192.1.1 is intended to be used by public internet hosts only.

Who Uses the 192.1.1 Network Range?

192.1.1 itself is not an IP address. An address consists of four parts, such as an address that's a part of this range, such as This dotted-quad format means that devices can't use 192.1.1 as their IP address in any way, even as a static IP address.

This IP address can't be used with routers or other interfaces that directly communicate with the public internet; this range of addresses is reserved for public use. This rule can be confusing because 192.1.1 looks like private addresses such as

However, on the internet, the IP address range through is registered to Raytheon BBN Technologies (originally called Bolt, Beranek, and Newman). This range includes every address between those two, such as,, and

When You Can Use the 192.1.1 Subnet

While an internet-facing network can't have an IP address starting with 192.1.1, it is okay to create an internal network starting with that subnet range. This is because, on an internal network, you're allowed to create any IP range you want, it doesn't have to start with That IP address is only a recommended standard for internal networks.

To create an internal network starting with 192.1.1:

  1. Log in to your home router as an administrator.

  2. Navigate to the Local IP Network menu, then set the router's internal IP address as

  3. This automatically sets the range for all internal devices on your home network to start with 192.1.1. If your devices are set up to get IP addresses automatically, each device is assigned an IP address starting with 192.1.1.

Even though this isn't a recommended IP address range for an internal home network, it is allowed and it will work fine. However, if you confused the recommended standard IP address for a home router of, it's a good idea to revert to using that recommended address instead.
