man pages for named.conf says "max-ncache-ttl <integer>" and only talks about default values and max values - no mention of minimum-value. 

Does "max-ncache-ttl 0;" mean never cache negative queries (queries resulting in NXDOMAIN) or does it mean cache negative queries forever?

Too lazy to test this option or look bind code :), hence posting here - apologies in advance..!!
