- At the risk of opening Pandorra's Box, this note suggests a change in the
- 2-character continent designator portion of the PBBS "H" hierarchical
- address field. An example would be the North America .NA portion of the
- packet address,
-
- K9DOG @ W6SIX.DE.USA.NA
-
- Let me state at the outset that I'm not convinced that we need to use the
- continent field. It seems to me that the country field by itself is ade-
- quate and that the packet BBSes can easily keep track of all the countries
- in the world. Let me also state that many of the issues addressed here
- arise because of constant confusion between the functions of addressing
- and routing.
-
- The correct continent to assign to many countries of the world is confus-
- ing and/or ambiguous. To cite some examples of problems which have already
- been identified:
-
- - 5B4=Cyprus in the Mediterranian is listed by the IARU (for WAC)
- and the ITU as Asia. Ditto 4X=Israel and JY=Jordan in the middle
- East.
-
- - Both TA=Turkey and and the Soviet Union have part of their coun-
- ties in Europe and part in Asia. 8Q6=Maldives is listed as both
- Africa and Asia. Several other countries are also "split".
-
- - Although DU=Philipines and YB=Indonesia are regarded as Asiatic
- countries, the are listed as Oceania, along with Australia and
- Hawaii. If you venture to 9M=Malasia, you may be in either Ocea-
- nia or Asia.
-
- - The Central American and Carribean countries are nearly all part
- of North America, including YV0, but not 9Y. Anyone care to guess
- what continent the southern part of HP=Panama is in?
-
-
- If the purpose of the continent portion of the "H"ierarchical address is
- to facilitate delivery of messages, then it is illogical to route Israeli
- and Jordanian traffic through the Orient. It is illogical to make automat-
- ed routing decisions for messages to Turkish amateurs based on whether the
- addressee is on the east or west side of the Straits of Bosporus.
-
-
- Stations in Israel and Cyprus already face this dilemma. Rather than using
- a .AS Asian address, they choose to use .EU European designator to avoid
- having their packet mail routed via the Orient. Some have suggested the
- use of a new continent designator other than .AS; One suggestion has
- been .ME (Middle East) but this has a serious conflict with the state of
- Maine.
-
- The Central Americans and the Carribean are both "legally" .NA but feel
- they need a separate geographic identity and both areas have independently
- suggested the use of .CA but this would conflict with .CA state.
- All this leads to my suggestion that the present 2-letter continent desig-
- nator must be changed. Either:
-
- (1) The present 2-character designator should be dropped because it
- it not really needed and there are too many ambiguities. Users
- will always try to use address quirks to force routing, so don't
- give them the chance to foul things up. The computers at the
- international mail gateways can easily handle the entire DXCC
- list.
-
- - or -
-
- (2) A new logical regional designator which allows sub-continent
- sized regions should be adopted.
-
-
- If a new, more flexible scheme is to be adopted, I'd suggest that new 4-
- character designators be chosen:
-
- - .NOAM, .SOAM, .CEAM, .CARB replacing the present .NA & .SA and
- solving the Central American and Carribean problem,
-
- - .ASIA replacing .AS for the Orient,
-
- - .MDLE for the middle-eastern countries like 4X, JY etc.,
-
- - Oceania divided into smaller areas like .NPAC, .SPAC, .AUST,
-
- - The Indian ocean (now partly in .OC and partly in .AF) be desig-
- nated .INDI,
-
- - .AFRI replacing .AF for Africa and .EURO replacing .EU for
- Europe,
-
- - .ANTR added for Antarctica,
-
- - Additional new designators added as needed for sub-continent
- sized logical areas.
-
-
- This scheme affords the logic of a 2-character field (.MD) for the
- "state", 3 characters (.DEU) for the country, & 4 (.AFRI) for the conti-
- nent/subcontinent and avoids conflicts between state-sized areas and
- continents. Who knows, a few decades hence a 5 character field
- (.EARTH, .VENUS) may be needed too!
