2. Abstract
|
|
|
|
This document defines the format of a new Experimental Resource Record (RR)
|
|
namely GL for the Domain Naming System (DNS), and reserves a corresponding
|
|
DNS type mnemonic and numerical code XX (decimal). This definition deals
|
|
with associating geographical host location mappings to host names within
|
|
a domain.
|
|
|
|
|
|
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
|
|
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY" and "OPTIONAL" in this
|
|
document are to be interpreted as described in RFC-2119.

3. Introduction
|
|
|
|
The ideal way to manage and maintain a database of information, such as
|
|
geographical location of Internet hosts, is to delegate responsibility
|
|
to local domain administrators.
|
|
|
|
This document resolves the problem of relating host information within
|
|
the DNS to geographical locations. This definition has been designed to
|
|
be easy for the person who administrates DNS for a domain. The author
|
|
hopes that the lack of requiring longitude, latitude and elevation
|
|
information and merely being able to enter address information, as you
|
|
would address a postal letter, will mean broad acceptance and use of the
|
|
GL resource record.
|
|
|
|
The availability of geographical location information will immediately be
|
|
able to benefit applications in network management, which would enhance
|
|
and supplement various network tools which currently exist.
|
|
|
|
The Domain Name System is ideally suited to provide geographic location
|
|
information. The information we desire to make available globally needs
|
|
to be maintained and updated locally (perfect for DNS).
|
|
|
|
Although several other attempts by various authors have attempted to
|
|
created resource records that would allow location information on host to
|
|
be stored and distributed, none, to the authors knowledge, have either
|
|
gained acceptance on a wide scale or made allowance for location information
|
|
that is not within the confines of the planet Earth.
|
|
|
|
4. The GL format
|
|
|
|
GL has the following format:
|
|
|
|
<owner> <ttl> <class> GL <Rdata>
|
|
|
|
|
|
4.1 Rdata Format
|
|
|
|
Rdata has the following format:
|
|
|
|
<string> <string>
|
|
|
|
The format of the RDATA field is two varying length strings separated by
|
|
a space character. The first, the hierarchical locator, then an address
|
|
string. Each is quoted (like all strings) only when it has spaces in it,
|
|
which will never be true for the first string, and almost always for the
|
|
second.

|
|
4.1.1 The Hierarchical Locator
|
|
|
|
The Hierarchical Locator contains the following components (each separated
|
|
by a period "."):
|
|
|
|
Astronomical Location - (Required)
|
|
A coded field defining the heavenly body within
|
|
the known Universe, where the machine resides. The most common
|
|
entry, "S3" is the planet Earth and is the only currently
|
|
defined location.
|
|
|
|
Man-made devices (Space Stations, Rockets, Probes, etc.) not residing
|
|
on planet Earth may have Astronimical Locations defined as well.
|
|
|
|
New locations MUST be registered with the Internet Assigned Numbers
|
|
Authority (IANA). Refer to section 6 for additional information.
|
|
|
|
Country Code - (Required)
|
|
|
|
The country code specifies the country the host computer resides
|
|
in. The code is a two character fixed length string and may only
|
|
be included within the Astronimical Location 'S3'. These codes
|
|
are defined in document ISO 3166-1 and are listed in Appendix A
|
|
for easy reference.
|
|
|
|
Postal Zone - (Optional)
|
|
|
|
This rdata component supplies the postal code (Zip Code) for the
|
|
location the host computer resides. For countries that have a
|
|
multi-segmented postal coding system, the segments should be
|
|
separated by period(s) ".".
|
|
|
|
This field may be omitted only if the country in which the host
|
|
machine resides does not use a postal coding system.
|
|
|
|
When all three Hierarchical Locator components exist for an DNS
|
|
entry, the position being defined is considered to be a "precise
|
|
position".
|
|
|
|
|
|
4.2 The Quoted String
|
|
|
|
This string should be entered as you would enter an address on
|
|
a postal letter within the country specified by the Hierarchical
|
|
Locator. The country code information should not be included within
|
|
the quoted string. This string is always required and must be
|
|
present in the RDATA field.
|
|
|
|
The quoted string may be used for both visual reference of the
|
|
physical address as well as by a software application to help
|
|
determine a more precise location of the host machine (if the
|
|
Hierarchical Locator lacks sufficient precision).
|

EXPIRES IN SIX MONTHS June 2000
|
|
|
|
|
|
The only instance in which any application should attempt to
|
|
interpret the quoted string is in a case where the country
|
|
code defines a country that does not use, or has not implemented
|
|
a postal code system.
|
|
|
|
No software or application should attempt to override a precise
|
|
position defined by the Hierarchical Locator with information
|
|
defined within the quoted string data.
|
|
|
|
|
|
5. Example(s)
|
|
|
|
Example 1 (with a postal zone defined):
|
|
|
|
donuts A 192.188.192.1
|
|
GL S3.US.45420.1910 "1425 Arbor Avenue, Dayton OH"
|
|
|
|
Example 2 (no postal zone):
|
|
|
|
lorinda A 129.122.1.1
|
|
GL S3.SR "Marthastrasse 64, Shawproject, Uitvlug, Parimaribo"
|
|
|

6. Registering New Astronomical Location(s)
|
|
|
|
New Astronomical Locations (ALs) MUST be registered with the Internet
|
|
Assigned Numbers Authority (IANA). IANA acts as a central registry for
|
|
these values. IANA may reject or modify the Astronomical Location
|
|
registration request if it does not meet the criteria as specified in
|
|
section 4.1.1.
|
|
|
|
Registration requests should be sent via electronic mail to IANA as
|
|
follows:
|
|
|
|
To: IANA@iana.org
|
|
Subject: Registration of a new Astronomical Location
|
|
|
|
The mail message must specify the proposed AL. Documentation defining
|
|
the AL and its proposed purpose must be included. The documentation must
|
|
either reference an external non-Internet standards document or an existing
|
|
or soon to be RFC. If applicable, the documentation should contain a
|
|
draft version of the future RFC. The draft must be submitted as a
|
|
RFC according to the normal procedure within a reasonable amount of
|
|
time after the AL registration has been approved.
|
|
|
|
IANA will not register a new Astronmical Location until an actual
|
|
computer requiring GL data in the DNS resides or will soon reside on a
|
|
heavenly body other than Earth.

7. Notes To Implementors:
|
|
|
|
7.1 Defining New Astronimical Locations
|
|
|
|
The astronomical location 'S3' is intended to be Sol-Three (i.e. the Earth).
|
|
The Earth is the 3rd large planet in the solar system. The Sun would be S0
|
|
(not that we'd have a computer there), but a solar observatory in orbit might
|
|
be S0-001. Our moon would be S3-1. Other letters and such for catalogued
|
|
objects. Additionally, the ISS and Mir space stations could use S3-001 (Mir),
|
|
S3-002 (ISS) now, if they get connected on IP.
|
|
|
|
This document only defines 'S3' however the authors strongly suggest that the
|
|
above nomenclature be followed.
|
|
|
|
|
|
7.2 Other possible uses for GL
|
|
|
|
The use of postal codes also is exactly what is needed for credit card address
|
|
authentication. Sites could (quietly) compare GL info provided on entries from
|
|
ISPs to what someone enters for additional verification purposes.

|

become out-of-date in this document. Any changes in the ISO specification
|
|
supercede this appendix and the ISO specification must be followed.
