For example router having 192.168.x.y/16 network attached, would not forward traffic to 192.168.*.0, which are legal IPs in CIDR world. - For compatibility, leave autoguessing of mask based on class. Reviewed by: andre, bz, rwatson Add support for IPv4 /31 prefixes, as described in RFC3021. To run a /31 network, participating hosts MUST drop support for directed broadcasts, and treat the first and last addresses on subnet as unicast. The broadcast address for the prefix should be the link local broadcast address, INADDR_BROADCAST. Approved by: re (kib) |
