Care to explain what that could possibly be? (I simply don't see an upside to making it easy to censor the internet by national identity).
Maintenance of "GeoIP"-databases becomes easier and less error-prone ?
Possible less out of date because of it.
We've seen complaints about those many times on this list.
There are much better ways to handle geolocation than reconfiguring the structure of the IP address space. See also: <http://tools.ietf.org/wg/geopriv/> <http://tools.ietf.org/html/draft-ietf-geopriv-http-location-delivery> <http://tools.ietf.org/html/draft-ietf-geopriv-lis-discovery> <http://tools.ietf.org/html/draft-ietf-geopriv-held-identity-extensions> Regardless of the technical merits of those specific protocols, which have been debated here and elsewhere, geolocation is an application-layer concept, and shouldn't be forced down onto the network layer. --Richard
