That is implementation specific and liable to change without notice,
and it's not something that matters anyway. But, at present the ISC
server allocates top-down, so it will allocate the highest address
Once all addresses have been used once, it re-allocates expired
leases on a least recently used basis - so once you get to this
state, address allocation will because pseudo random.
