Hi Tony, The main reason I can think of is compatibility. This (BULK-like functionality) is actually happening today. In fact several vendors have been offering this very feature in various incompatible ways simply because of the demand for it. Why not offer it in a way everyone can benefit? We continue to receive requests for this feature and it just made sense to offer it in a way that zones could be AXFR'd back and forth regardless of vendor and interoperate in a compatible manner. > > Where I work, we bulk populate reverse v4 DHCP pools just so we know > that they are pools.

We have literally millions of $GENERATE-based synthesized records on the IPv4 side of the house. We see a variety of uses, sure a majority are pools and rfc2317 delegations but they are all still there eating memory whether used or not.
