Jens-Peter and Gerald are correct.  The BIND9 ARM gives a good
bit of "do this" advice.  Add 0x7fffffff (2^31-1), don't worry
when wraparound gives you a "lower" number, and you'll be on your
way.

If you're interested in the how and why, check out RFC1982:

	http://www.rfc-editor.org/rfc/rfc1982.txt

This explains in depth the sequence space arithmetic used in DNS.
