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.
