Something that I have often wondered is how folks would feel about publishing some sort of geo information in reverse DNS (something like LOC records, with whatever precision you like) -- this would allow the folks that geo stuff to automagically provide the best answer, and because you control the record, you can specify whatever resolution / precision you like.yes!FWIW, there has been some work in the IETF on creating protocols to allow pretty rich location information to be published in reverse DNS. Basically, you publish a NAPTR pointer to a location server [1] where an interested client can ask for the location of a specific IP address [2][3]. (Publishing location in this way is a requirement in several systems for VoIP 9-1-1 around the world to allow first responders to ask networks for location. See for example the NENA i3 architecture in the US and a similar "Canadian i2" for Canada.) The location representation these protocols use is a profile of the Geospatial Markup Language, so you can represent anything from a simple point to full GIS-like layers; you can also represent civic addresses (i.e., postal addresses) directly.
surely, with its vast talents, the ietf can make this more complex. after all, look at the inflate-and-embellish stupidity that made the simple idea of bgp communities for data collecion, completely ueless, draft-meyer-collection-communities-00.txt </sarcasm> i just wanna deal with a cidr block for stupid simple thing, not boil the ocean. and we have LOC RRs. no brilliance or inventiveness needed. randy
