192.168.0.0 is the start of the private IP address range that includes all IP addresses through 192.168.255.255. Because of this, this IP address is usually not used on a network (e.g. a phone or computer is not assigned this address).

However, some networks that include 192.168.0.0 in their network but do not start with this address, can use it for a device without any issues.

For perspective, one common IP address assigned to home routers is 192.168.1.1.

This IP address is used because the router is on the 192.168.1.0 network. In the same way, routers on the 192.168.0.0 network are usually assigned the local, private IP address of 192.168.0.1.

Why Most Devices Don't Use 192.168.0.0

Each Internet Protocol (IP) network consists of a continuous range of addresses. The first address number in the range is used by the protocol to designate the network as a whole. These so-called network numbers normally end in zero.

An address like 192.168.0.0 becomes unusable for any other purpose once it is established as a network number. If an administrator attempts assigning 192.168.0.0 to any device on that network as a static IP address, for example, the overall network will stop functioning until that device is taken offline.

Note that 192.168.0.0 can still theoretically be used as a device address if that network set up with a very large address range (for example, a network that spans from 192.168.128.0 through 192.168.255.255).

That's why devices having IP addresses ending in zero are very rarely seen on networks, with the exception of 0.0.0.0.

How Big Is the 192.168.0.0 Network?

The size of the 192.168.0.0 network depends on the network mask chosen. For example:

  • 192.168.0.0/16: Ranges between 192.168.0.0 and 192.168.255.255 with 65,534 possible hosts
  • 192.168.0.0/18: Ranges between 192.168.0.0 and 192.168.63.255 with 16,382 possible hosts
  • 192.168.0.0/24: Ranges between 192.168.0.0 and 192.168.0.255 with 254 possible hosts

Home broadband routers that run on the 192.168.0.0 network most commonly have 192.168.0.0/24 as their configuration, which means they normally use 192.168.0.1 as their local gateway address. This set up allows the network to assign up to 254 devices with a valid IP address, a number that's extremely high for home networks but entirely plausible based on the configuration.

Note: Home networks can only handle so many devices at once; ones that have more than even 5-7 devices connected to the router at once often notice massive performance issues. This is not due to the limitations of the 192.168.0.0 network but instead things like signal interference and bandwidth sharing. 

How 192.168.0.0 Works

The dotted decimal notation of IP address converts the actual binary numbers used by computers into a human readable form. The binary number corresponding to 192.168.0.0 is this:

11000000 10101000 00000000 00000000

Being a private IPv4 network address, ping tests or any other connection from the Internet or other outside networks can not 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.

Alternatives to 192.168.0.0

Many other addresses ending in zero can conceivably be used instead; the choice is a matter of convention.

Like what's mentioned above, home routers are usually installed on the 192.168.1.0 network instead of 192.168.0.0, which means the router probably has a private IP address of 192.168.1.1.
