- That's the default route for IP multicasting. Note that it's a Class D network
- number. IP multicasting is described in RFC1112:
-
- 1112 Deering, S.E. Host extensions for IP multicasting. 1989 August; 17 p.
- (Format: TXT=39904 bytes) (Obsoletes RFC 988, RFC 1054)

- It should make for some interesting applications, once enough vendors pick it
- up (I've heard Ultrix has it as well, but don't know for sure).

- P.S. - The 224.0.0.0 route should not be adversely affecting you; things that
- don't understand it will just ignore it.
