I'll freely admit to only dabbling in IPv6 on my home network and having done a very little bit of nosing around in the KAME codebase, so I could you give some references for this stance. Some RFCs or other docs delivered from the mount saying users are never supposed to see these? The fact that the RFCs specify special presentation formats for these addresses kind of just made me assume that they were meant for humans to see and use. But we all know assumptions can be way off. > If you find an application which does this, don't hesitate to kick the > coders to fix their stuff. OK, so, is this, $ netstat -an | fgrep ::ffff: tcp 0 48 ::ffff:207.88.152.51:22 ::ffff:207.88.153.67:3376 ESTABLISHED $ uname -srvmo Linux 2.6.17-1.2142_FC4 #1 Tue Jul 11 22:41:14 EDT 2006 i686 GNU/Linux On a plain ol' dual stack Linux box living on an IPv4-only network kosher? Or does kicking need to be done? BÂinformation contained in this e-mail message is confidential, intended only for the use of the individual or entity named above.
