ISC DHCP does use a hash to pick the address or prefix to use.

Thnx Shawn, this is good to know
I did the initial DHCP_PD tests with a relatively small pool (64 prefixes
and 2 clients) and and I saw incrental address assignment (the server
giving out first, then the second etc).I will perform the tests again with
bigger pool + more clients to get a better understanding.
For DHCP_PD in relay mode do you know on which fields does the ISC bases
its hashing (just DUID?)
Regards
Victor
