Just curious - and if this is way too far off topic here please let me
know (off list obviously :)): what is the reason you cannot do an
initial DNS lookup and then cache the results internally?

Wouldn't that be a good policy to adopt when it comes to time-critical
services? NTP is quite time critical by nature, I don't know about
SNMP and DNS is an obvious case - hard to ask about something when
there's no place to ask, and especially for computers.

Again, if this is way too far from the 6bone list's subject, please
let me know.

this is very unfair and insulting to the beasts: a beast can never be
so cruel as a man, so ingeniously, so artistically cruel.''
