Out of curiosity: what if it's a /16 or /8 network? Do those also get built as 24 bit files, or can they be built differently? I seem to recall seeing an option for a reverse lookup file with hosts declared as: x.y PTR host.domain.tld. Does that work, or was that an old format that's been deprecated, or would it never have worked?
