ipv4-cidr - An IPv4 address in CIDR notation

JSON Data Type: string.

The ipv4-cidr format represents an IPv4 address in CIDR notation, with the address and prefix-length syntax described in RFC4632.

The address MUST be a valid ipv4 address, and the prefix length MUST be a decimal integer from 0 to 32, inclusive. A plain IPv4 address without a prefix length is not accepted.

Examples of valid values include 10.0.0.0/8 and 192.168.1.0/24.
