IP address 192.168.1.0 represents the 192.168.1.x range of local area network (LAN) addresses where x is any number between 1 and 255. It is the default network number for home broadband routers that take 192.168.1.1 as their default address.

Why Computers Hardly Ever Use 192.168.1.0 as an Address

Internet protocol organizes each network into one continuous address range. The first number in the range serves a special purpose in IP; it is used by routers to support the 192.168.1.x network as a whole.

When 192.168.1.0 (or any other address) is configured as a network number, it becomes unusable for any other purpose. If an administrator gives any device on the 192.168.1.0 network that address as a static IP address, for example, the overall network stops functioning until that device is taken offline.

Note that 192.168.1.0 can still be safely used on the 192.168.0.0 network if that network is set up with a large enough address range of more than 255 clients. However, such networks are rare in practice.

How 192.168.1.0 Works

192.168.1.0 falls within the private IP address range that starts with 192.168.0.0. It is a private IPv4 network address, meaning that ping tests or any other connection from the internet or other outside networks cannot be routed to it. 

As a network number, this address is used in routing tables and by routers to share their network information with each other.

The dotted decimal notation of IP address converts the actual binary numbers used by computers into human readable form.

The binary number corresponding to 192.168.1.0 is

11000000 10101000 00000001 00000000

192.168.1.0 should not be assigned to any devices on a home network.

Alternatives to 192.168.1.0

A home router is typically installed at 192.168.1.1 and supplies only higher numbered addresses to local clients—192.168.1.2, 192.168.1.3, and so on.

IP address 192.168.0.1 works well and is sometimes used as a home network router's local IP address. Some people mistakenly reverse the last two digits and look for 192.168.1.0 on their network instead of the correct address.

All network in the private IP ranges work equally well. 192.168.0.0 is easier to remember and the most logical starting place to set up a private IP network, but 192.168.100.0 or a person's favorite number instead of 100 and less than 256 works also.
