| Definition | The IP address 192.168.0.0 is the start of the Class C private range. Broadband routers and other network gateways reserve this address to reference the private network. You should not attempt to set 192.168.0.0 as the IP address for your router or any computer as it will not function properly. Some routers are configured instead to use 192.168.0.1 by default that is the first usable address in the range.
