Yes would be nice, and that WAS what I expected.  Sadly someone 
decided to use DHCP to collect an IP address from the nearest IPv4 
DHCP server and stuff that onto a randomly selected prefix hoping 
that there would be no clash.

I can assure you, when this box autoconfed, it took me ages to find 
it, cause in my infinite wisdom I assumed that Mac Address was the 
suffix and I already 'knew' the prefix!

We may have some time to go!
