I don't know what the latest word is, but the domain/subdomain naming conventions outlined in RFC819 are too restricting. I agree that a geographically related addressing scheme could be appealing, but it does have problems. Who, for instance, is responsible for creating the addresses, or ensuring their uniqueness. Likewise, with sparce electronic networks, a machine down the street may be harder to get to than one in the next state. At least organizationally structured domains make the addresses of electronically "near" machines similar, reducing the address -> routing burden for small machines. Perhaps someday there will be a strongly coupled network which will make geographical naming practical. My personal "flame" is that (at least as of RFC819), it does not seem to be possible to create sub-domains which are largely independant of their surrounding domains. The requirement that local host and sub-domain names must be disjoint from the local host and sub-domain names of all "ancestor" domains is only enforcable if coupled with strong policing of name allocation. Relaxing this so that local names need only be disjoint from the names of its "ancestor" domains, and not their children, would make name allocation much simpler, and would only make outgoing addresses one domain longer. That is, instead of omitting the entire common portion of source and domain addresses, the sender would omit all but the least most encompassing domain name. This would also make it easier for small, local domains to get access to the world. All they need is for a larger domain to "sponsor" them, and route all mail to one or two gateways known to the sponsoring network. Routing within the smaller domain need only be a concern of the gateways. Let's here it for the small guy! Am I flaming to no end? Has this already be suggested? Please let me know. -- jonah (Jeff Lee @ Dept. of Comp. Sci., The University of Western Ontario) UUCP: ...!decvax!{utzoo|watmath}!deepthot!jonah MLNET: jonah@deepthot.UWO
