3 bits as a prefix would work perfectly fine IMHO. This gives us an entire 32-bit space PER CONTINENT. As I noted before I don't think the penguins really need that many Ips in Antartica, but that could always be set aside. In addition, there's an extra set (only 7 continents at last count) for extra-terrestrial expansion or other needs.
And, that gives the ability to filter entire continents out if necessary. The country code (ITU) isn't really a bad idea either, but I'm just thinking less overall binary bits.

There are under 200 countries on the whole planet, so that's not a huge number of bits... ===== David Barak -fully RFC 1925 compliant- __________________________________ Do you Yahoo!?
