Unless you're running in authoritative mode, they're kept only in 
memory.  This is not something you can edit live.

If you are running in authoritative mode, then for the zones that you 
serve authoritatively, they are loaded from disk into memory, where they 
are used to actually serve data.  Again, you can't edit these live -- 
you can edit the text files and make BIND reload the zones, but that's 
not editing the data live.

If you've got any other questions on BIND, let me know.  I've been 
mucking about with it since the early 90s, and I'll be glad to share 
whatever experience I can.
