| 110 | It consists of an address part and a mask length part. |
| 111 | The address part is only used up to the number of bits |
| 112 | specified in the length (1-27, given after the slash). |
| 113 | |
| 114 | For example the value 10.10.159.211/20 will mean an |
| 115 | effective range from 10.10.144.0 - 10.10.159.255 and |
| 116 | a count of 2^12 = 4096. The last 12 bits (32-20=12) |
| 117 | of the address is ignored because it is not within the |
