I cannot figure out where this comes from. Most applications don't need to do anything different for SL than they are doing for globals. If your node belongs to only one site, SL's behave exactly like global addresses inside the node. A client application establishing a connection would just get the address from DNS (or whatever source), and use it as is, wether SL or not. The only cases, that might require additional work, are applications that pass own address inside the protocol. I can think one example of such: IRC and activating client-to-client connection. When doing so, an IRC client sends an IRC private message containing it's own address and port over the IRC network. A careful client, which is prepared to work in multihomed host, would extract own address from the connection that is being used for the server. - however, the server might be on SL address, but connected to outside world. Then this strategy would fail. The minor additional work in this case in IPv6 world, would be to ask highest scope address that is available (although things get a bit fuzzy, if node is truly multihomed with multiple global addresses on different interfaces..) - above is no way different situation that currently exists, if your IRC server is on 10.x.x.x address. If you have both 10.x.x.x and some global address, client should send the global address, and not the address used to talk with the IRC server. - if you don't have global address (either IPv6 global or IPv4 global), you are hosed any way (unless the other client is also same site, in which case all works just fine again). -------------------------------------------------------------------- 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] --------------------------------------------------------------------
