There are 959000 </24 inetnum objects vs 1101000 total inetnum objects vs
139000 domain objects vs 137000 delegations currently in the RIPE
database/zone files.

( Note that some domain objects are occluded by other domain objects )

We have ccTLD zones secondaried on the same servers with more than a
million DNS records.

Agreed.  ( DNS updates by the NCC for dynamic addresses has LIR customers
directly contacting the NCC written all over it, to say nothing of how we
handle this in the database )
