Somewhere I read something like: "The format YYYYMMDDnn" is often used for the serial number. We know this wil break in the year 4294, but we are not worried about that." > what happens if we have a bigger number? > then bind takes it like modulus 2^32? I once put in an extra digit in the serial number. This made a secondary use a serial number, which was larger than mine, and could probably be the modulus 2^32. I had to call the hostmaster there (A "3.rd secondary" hosted at our uplink) to get the zonefile removed, so the right one would be reloaded. > or it is forbidden to > have a bigger number?
