For example, the legacy "Class B" network 172.16.0.0, with an implied network mask of 255.255.0.0, is defined as the prefix 172.16.0.0/16, the "/16" indicating that the mask to extract the network portion of the prefix is a 32-bit value where the most significant 16 bits are ones and the least significant 16 bits are zeros. Similarly, the legacy "Class C" network number 192.168.99.0 is defined as the prefix 192.168.99.0/24; the most significant 24 bits are ones and the least significant 8 bits are zeros. http://tools.ietf.org/html/rfc4632 Classless Inter-domain Routing (CIDR): The Internet Address Assignment and Aggregation Plan -- Gabor HALASZ <[email protected]> _________________________________________________ linux lista - [email protected] http://mlf2.linux.rulez.org/mailman/listinfo/linux
