BIND imposes no limits on file/record sizes. Otherwise zones
like .com. would never be loaded and you're never likely to
deal with zones of that size. The only limits are the ones imposed
by the operating system, the memory you need and the pageswap
space that you need when you load all of your zones into memory
and respond to queries.
