192.168.1.0 Private Network IP Address Notation

Should you use IP address 192.168.1.0 on your home network?

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's the default network number for home broadband routers that take 192.168.1.1 as their default address. However, 192.168.1.0 should not be assigned to any device on a home network.

If you can't access a router to log in as admin and make changes (for example, to create a Wi-Fi network or manage DNS settings), the router IP address may have been mistyped. To access the router, turn the IP into a URL, for example, http://192.168.1.1.

Why It's Rare to Use 192.168.1.0

Internet protocol organizes each network into one continuous address range. The first number in the range serves a special purpose in IP. It's 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 assigns 192.168.1.0 as a static IP address, for example, the network stops functioning until that device is taken offline.

192.168.1.0 can be safely used on the 192.168.0.0 network if that network is set up with an 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's 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 the network information with each other.

The dotted decimal notation of IP address converts the binary numbers used by computers into human-readable form. This is the binary number corresponding to 192.168.1.0:

11000000 10101000 00000001 00000000

192.168.1.0 Alternatives

A home router is typically installed with 192.168.1.1 and supplies only higher-numbered addresses to local clients, for example, 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 networks in the private IP range 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 any number less than 256 works as well.
