I don't know what you mean by that. The number of servers does not
depend on the size of the address space.
That doesn't compute John, unless a 30+ second dns lookup time would be
tolerable.
Why would a DNS lookup take 30 seconds ?
Anyway, this is irrelevant. Registries who assign address blocks do not
manage DNS lookups. They just manage delegations to the organizations
which manage reverse DNS zones. Besides, a reverse DNS zone does not
have to serve PTR records for all IP addresses in the block.
