I would think if you find something that tracks IPv6, that's all you need. You can represent the whole IPv4 space with IPv4-mapped IPv6 addresses, :ffff:a.b.c.d.
This is certainly true. Let's not forget that a simple thing that strips the :ffff: and converts the remaining bits from hex to decimal (at least visually) would be needed to keep the clue impaired up and running. :)
Any application which is visualizing IPv4 adresses using either ::ffff:x.x.x.x or ::x.x.x.x is wrong(tm). Those addresses should never ever be shown to the user or used in any way as a textual representation (that includes for instance logfiles, XML files, and other such
If you find an application which does this, don't hesitate to kick
things). 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. the

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? B¼information contained in this e-mail message is confidential, intended only for the use of the individual or entity named above.
