The "for private use" address ranges are: Class A: 10.0.0.0 through 10.255.255.255 (one network with 16 million addresses, or smaller subnets as appropriate). Class B: 172.16.0.0 through 172.31.255.255 (16 networks with 65536 addresses each, or larger or smaller subnets as appropriate). Class C: 192.168.0.0 through 192.168.255.255 (256 networks with 256 addresses each, or larger or smaller subnets as appropriate). In each case, the "all zeros" and "all ones" addresses within the network are reserved. The ones which actually work with a particular DSL modem, cable modem, router, etc. will depend on how it is configured.
