Description

Validates that you provide a CIDR in one of the following valid ranges.

    127.  0.0.0 – 127.255.255.255     127.0.0.0/8
     10.  0.0.0 –  10.255.255.255      10.0.0.0/8
    172. 16.0.0 – 172. 31.255.255    172.16.0.0/12
    192.168.0.0 – 192.168.255.255   192.168.0.0/16

Subnets can be smaller (e.g. 192.168.0.0/17 is valid) but not larger (e.g. 192.168.0.0/15 is invalid). Single hosts (i.e. /32s) are invalid. Host bits are generally ignored (i.e. 192.168.1.2/16 is considered valid)
