What is 192.168.0.0? Can I assign this IP address to a network card?

Frequent questions: what is 192.168.0.0? What an unusual IP address ending with zero? Can I assign 192.168.0.0 IP address to my router, the network card of my computer or android phone? So let us look at what is this.

What is 192.168.0.0

As you may know every subnet has three service IP addresses:

  • subnet IP,
  • multicast IP,
  • default gateway IP.

192.168.0.0 is a subnet IP address in this case.

Examples

1) If computers, smartphones and tablets on a network use IP addresses like 192.168.0.11, 192.168.0.35, 192.168.0.50 with subnet mask 255.255.255.0 the subnet address is 192.168.0.0.

2) If network devices’ IP addresses are 192.168.1.15, 192.168.1.100, 192.168.1.101 with subnet mask 255.255.255.0 the subnet address is 192.168.1.0.

Typical LAN address assignment model

Today a home or small office computer network structure usually looks like this:

  • subnet IP: xxx.xxx.0.0,
  • network devices’ addresses: xxx.xxx.0.1xxx.xxx.0.253,
  • default gateway: xxx.xxx.0.254,
  • multicast: xxx.xxx.0.255.

Can I assign 192.168.0.0 address to a network card of my laptop or PC?

No! You shouldn’t assign 192.168.0.0 to any network device (even to your router) because in this case your network may function improperly and you may encouner various problems. The nearest example: your device may be unaccessible over the network.
