Re: DHCP options for civil locations

Thanks for the comments. In general, I think I agree with your approach.
My interpretation is that each country would need to define what nth
level means. For example, Portugal has regions, but nobody uses them for
addressing. They would be a 2nd level designation, but redundant.

That's already there, as CountryCode. Since every address will have that
and it has a fixed length, I figured it would be a waste to encode it as
TLV.

http://www.bitboost.com/ref/international-address-formats.html has lots
of information on addressing topics (or weirdnesses, if you like).

For the purposes of locating people and housess, I don't think it's
necessary to make these r distinctions - we're not trying to draw maps
here. These are somewhat arbitrary.
