See: > http://www.microsoft.com/technet/itsolutions/network/evaluate/ > new_network.mspx This should hardly be a surprise. The inability of the IETF to accept as legitimate real world security concerns at the time 2462 was written was as notorious as its insistence on certain irrelevant concerns being absolute. It the real world I am actually very concerned if someone is able to determine my MAC address. It opens up a significant amount of information about my internal network that in the real world I have no intention of sharing. During the 1990s many people, myself included mistook applying cryptography for security. In the real world what network managers want to do and will insist on having tools to acomplish is to guard the boundary between the internal and external network as closely as possible and to prevent any piece of unnecessary information crossing that barrier in either direction. It is certainly a mistake to consider this practice a sufficient condition for security but anyonje who does not understand that it is a necessary party of a security strategy has little to contribute to today's security architecture.
