All of 127/8 is reserved for loop-back (per RFC 1122), but it's traditional to use only the first host address in that range -- 127.0.0.1 -- for that purpose. It dates back to (at least) the original BSD TCP/IP implementation. It's handy in that applications can assume it's valid for local communication without having to result to horrific hacks, like trying to do a name service lookup on the local host name. In OpenSolaris, all local addresses essentially behave the same with respect to local loop-back behavior. -- James Carlson 42.703N 71.076W <carls...@workingcode.com> _______________________________________________ networking-discuss mailing list networking-discuss@opensolaris.org
