There's a nice algorithm depicted in RFC4193 for that purpose. The fc00::/8 block was originally meant for a global unique private prefix but didn't attrack much support. The idea was to have a NIC assigning prefixes out of fc00::/8 to make them unique. Now we have only fd00::/8 with some probability of overlapping ranges.

Are they using the algorithm in RFC4193?
