IPv6 to IPv4

I am running FreeBSD 4.4

I need to find the IPv4 address given a machine's IPv6 address. Anybody have any ideas on how to do this?

Is there a mapping from IPv6 address -> IPv4 address? Or should I rely on system calls?


PS The bigger picture - is that I want to contact IPv6 machines using Webmin (which does not support IPv6 and can do this only with IPv4 addresses)

The automaticly configured IPv6 addresses are based on the MAC address, unless they're being handed out by rtsol or staticly assigned. You can, however, create an IPv6 tunnel to encapsulate IPv4 traffic.

$ man gif

should yield more details.
