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.

10 years ago we didn't have the RIR system in place to help us with geographic addressing. Today we do. Now you might be able to convince me that we could achieve similar goals by putting together route registries, RIRs and some magic pixie dust. As far as I'm concerned, geographical route aggregation is necessary for the v6 network to scale. It will happen, the only question is how we solve the problem.
What exactly would be so bad about taking a page from the PSTN and using a country-code-like system? 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!?
