Whether it's a /24 for f-root or a /20 doesn't really make a difference- it's a routing table entry either way- and why waste addresses.

I once suggested that due to the odd nature of the root name server addresses in the DNS protocol (namely, that they must be hardwired into every caching resolver out there and thus, are somewhat difficult to change), the IETF/IAB should designate a bunch of /32s as "root server addresses" as DNS protocol parameters. ISPs could then explicitly permit those /32s.

However, the folks I mentioned this to (some root server operators) felt this would be inappropriate.
