IP classes
The private IP address ranges of classes A, B and C are listed in the following table.
| Private IP address ranges | Standard subnet mask |
Class A network | 10.0.0.0 to 10.255.255.255 | 255.0.0.0 |
Class B network | 172.16.0.0 to 172.31.255.255 | 255.255.0.0 |
Class C network | 192.168.0.0 to 192.168.255.255 | 255.255.255.0 |
Note:
All of the above listed address ranges (compliant with RFC 1918) are not available on the Internet, i.e. they are reserved for private use. If you do not have an official IP address, only use these private address ranges!
Notes on the Subnet mask
The program only allows valid subnet masks. A valid subnet mask must consist of a contiguous series of 1 bits followed by 0 bits. At least the MSB (Bit 32) must be 1 and LSB (Bit 0) 0 in order for the mask to be valid. See also the previous chapter IP Classes.
Examples of invalid subnet masks: | Binary format: |
|
255.255.255.255 | 1111 1111.1111 | 1111. 1111 1111.1111 1111 |
0.0.0.0 | 0000 0000.0000 | 0000.0000 0000.0000 0000 |
255.255.15.0 | 1111 1111.1111 | 1111.0000 1111.0000 0000 |
| *MSB: Far left in the table above | |
| *LSB: Far right bit | |
