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.
