This has been around for twenty years.  The following is an appendix
from the specs in the mid 1990's, including the 4-letter continent
identifiers.

Appendix B: Hierarchical Addressing Protocol

This is an extract and update from the original document. The specific
regional and area designators have been removed, since they are
determined on a local basis.

Introduction

The TAPR BBS Special Interest Group recommends the adoption of the x.3.4
hierarchical address protocol.

After discussion of previous articles on hierarchical addressing
standards (1,2) and taking into account international issues of
regional/state name sizes, the TAPR BBS Special Interest Group
recommends the adoption of the x.3.4 standard on an international basis.
x is defined as 2, 3, or 4 letter region names as defined by the country.

Examples of x.3.4:

@WA6GVD.CA.USA.NOAM
@EA2CMO.EAZ.ESP.EURO
@F5JGK.FAQI.FRA.EURO

Regional identifiers may be duplicated in different countries (i.e. AK,
Alaska, USA, could be used in another country as a regional identifier);
however, Country and Continental identifiers SHOULD NOT be used as
regional names.

It is important to note that there is a distinct and significant
difference between HIERARCHICAL ADDRESSES and FLOOD DESIGNATORS.
Hierarchical address elements are common to all messages (bulletins, P
and T types) and are the foundation of the digital forwarding system.
Flood designators are used for routing and filtering bulletins.
Geographical flood designators are likely based upon hierarchical
address elements. It is therefore important that any attempt to
establish standards concentrate first on hierarchical address elements.
Standards for flood designators can follow.

It is the purpose of this document to generate a changing recommendation
that reflects current hierarchical routing. Reference Tables at the end
will be changed as necessary to reflect current configurations within
the international BBS network. These tables will need to be changed and
updated in order to meet future needs of user and sysops.


Hierarchical Routing Syntax Summary

This summary uses a modified Backus-Naur form to summarize the syntax
for hierarchical addressing. Optional fields are shown within square braces.

Hierarchial_address = bbs.["#"area.]region.country.continent

bbs = Callsign as defined by the local communications authority.

Area = additional identifier depending on local requirements.

Region = As defined by the local country. This is normally the
abbreviation for the state, province, prefecture, etc.

Country = 3-character country identifier as defined by ANSI X.12 and
EDIFACT. Published in ISO 3166-1981(E/F).

Continent = 4-character continental identifier from the following table.


TABLE 1: Continent Identifiers

EURO   Europe
MEDR   Mediterranean
INDI   Indian Ocean including the Indian subcontinent
MDLE   Middle East
SEAS   South-East Asia
ASIA   The Orient
NOAM   North America (Canada, USA, Mexico)
CEAM   Central America
CARB   Caribbean
SOAM   South America
AUNZ   Australia/New Zealand
EPAC   Eastern Pacific
NPAC   Northern Pacific
SPAC   Southern Pacific
WPAC   Western Pacific
NAFR   Northern Africa
CAFR   Central Africa
SAFR   Southern Africa
ANTR   Antarctica
