Do you change the network interface that often? Updating the DNS once
in a while does not look like a huge burden.

You could force the old MAC address on the new interface. Of course if
you still use the old interface elsewhere you will be in trouble.

... and you still have the same DNS problem in this case, right?


You seem to have an incredibly dynamic network environment, can you
give more details about it?


PS: this does not look specific to IPv6
