Comment (by anon):

 Suggested tests to confirm working clamps:

 224.0.0.0/3 clamped to 224.0.0.0/8
 10.254.0.0/8 clamped to 10.254.0.0/16
 10.11.12.13/32 NOT clamped (left at /32)
 10.0.0.0/24 NOT clamped (leading zeroes not indicative of useful network
 prefix length)

 Test that invalid CIDR netmasks result in warning but are accepted.

 IPv6 CIDR tests? or perhaps 4in6 CIDR verifications? These may be useful.
