Is it worth mentioning that large TTL values are trimmed to
something smaller by BIND.

And as anyone familar with 32 bit Unix, 2^31 seconds is 68
years (More or less).

Another one to remember next time people ask "why dig rather
than nslookup" - your vendor nslookup may not handle unknown
RR records well, or may not know some common record types.

Do they really want BIND as a secondary to a DNS utilising
WINS? If your working on the name service now, it is
probably a good time to chuck out WINS, it was a naff
solution from day one, typical M$ fudge.
