All thanks for the information. I'll be using the "40 bit pseudo random
thing" since it seems to be the smart thing to do, using the SIXXS tool.
One may hope that something will become the "official" way to generate
these numbers (perhaps the above mentioned tool).
Someone advised me to use GUA instead of ULA. But since for my purposes
this is used for an IPv6 LAN would ULA not be the better choice?
Thanks,
Jeroen
