When allocating a "new" IP from the pool, any hostname formerly associated to it remains attached. Releasing an IP back to the pool should remove any hostnames.
Doesn't the web interface prevent release of an IP if it has hostnames?
I'm uncertain; I ran into this I think after a deleted /project/ ended up with IPs back in the pool.
