Depends who you ask. Again, RFC1122 says (section 1.1.1), A host is generally said to be multihomed if it has more than one interface to the same or to different networks. And also section 18.104.22.168, A multihomed host has multiple IP addresses, which we may think of as "logical interfaces". These logical interfaces may be associated with one or more physical interfaces, and these physical interfaces may be connected to the same or different networks. As far as a "multihomed host" is concerned, RFC1122 sure seems to call anything with multiple IPs multihomed. Multihomed is a trait of the host independent of any network topology around the host. But whatever. It just means people need to be clear what they are talking about when they say "multihomed." As is clear from this thread, there is not clear agreement on what the precise meaning is. -- Crist J. Clark firstname.lastname@example.org Globalstar Communications (408) 933-4387
