I'm not sure I understand your last parenthesized comment. Are you worried that an application could choose a destination address based on source address assumptions that are different than those of the kernel's default source address selection mechanism? In that case, the application should bind to the source address to be sure it gets the one it wants right? I could be misunderstanding what you've said. > > The extra steps may not harm of course (extra work..).

The source address selection mechanism is still useful in the absence of the destination address ordering. In any case, there is no guarantee that applications will use the destination addresses in the order returned from name lookups. Also, users or administrators may want the ability to turn off the destination address ordering mechanism in order to preserve some sort of ordering returned by the server (DNS round-robin for example). The destination address ordering mechanism needs some deterministic source address mechanism to use as input, otherwise only rules 1, 6, 7, and 8 make any sense. So perhaps a subset of the destination address ordering mechanism would be useful without the source address selection bits. -Sebastien -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
