The actual records should have TTL's of a few hours, perhaps a day.
The rest of the hierarchy can probably get away with longer TTL's,
especially close to the root. It's the same thing with the root in
regular DNS: You can cache the set of records in the root zone for a
long long time, since noone is going to suddenly move all the .com
nameservers.
