RFC1918 states the following blocks of IPv4 addresses that can be used in a Local Area Network. These are "private" address ranges that do not overlap with public IP addresses.
| Network/mask | Class | First usable addr. | Last usable addr. |
|---|---|---|---|
| 10.0.0.0/8 | Class A | 10.0.0.1 | 10.255.255.254 |
| 172.16.0.0/12 | Class B (x16) | 172.16.0.1 | 172.31.255.254 |
| 192.168.0.0 | Class C (x256) | 192.168.0.1 | 192.168.255.254 |
