The real question is why?

If you were a mobile phone company planning to put all your
subscribers into a flat namespace, I'd still think you were mad,
but I'd appreciate why you had 10 million records.

The largest routine use large zones other than .COM is I suspect
the relay blocking lists, one day they will realise they can
break IP addresses up by octets, and split their 17 MB zone into
250 smaller zones.

BIND tries to keep everything in memory, Bill is right this
could require a 64bit architecture, you'll be pushing some 32bit
systems. I'm sure less memory hungry solutions exist.
