RFC Editor's Note
This RFC is an independent submission that discusses a possible
convention for allocating domain names based on corporate and other
names as registered by law.
It appears to depend on corporations changing their domain names from
their present form to more cumbersome handles, such as changing
cisco.com to cisco-systems.co.ca.us or ibm.com to international-
business-machines.co.ny.us, without giving them an incentive to do
so, such as deprecating the .com and .net gTLDs. It also appears to
legislate the structure each national registry applies to its name
space, something which the document itself asserts is within national
purview and not for global standardization.
It may not be politically feasible to implement as described.

1. Introduction
The purpose of this memo is to focus discussion on the particular
problems with the exhaustion of the top level domain space in the
Internet and the possible conflicts that can occur when multiple
organisations are vying for the same name. The proposed solutions in
this document are intended as a framework for development, such that
a general consensus will emerge as to the appropriate solution to the
problems in each case, leading eventually to the adoption of
standards.
2. Overview of the domain space
Presently the domain space is organised as a heirarchical tree-
structured namespace with several top level domains (TLDs), and sub-
domains beneath them. The initial TLDs allocated and rationale are
documented in RFC 920 [1].
The TLDs are functionally split up into 'generic' top-level domains
(gTLDs) and two-letter ISO 3166 country domains for every country in
which Internet connectivity is provided. The allocation of sub-
domains under these TLDs is entirely up to the registry for that TLD.
The registry may decide to allocate further levels of structure or
merely allocate domains in a 'flat' manner.

1. Flat gTLD 2. Heirarchical country 3. Flat country
In the example we see that the gTLDs are inherently flat, as
organisations are allocated domain names directly under the TLD.
With the country domains however, the domain allocation policy can
vary widely from country to country, and it does. Some may choose to
implement a functional sub-structure mirroring the gTLDs, some may
choose to implement a geographical sub-structure, and some may choose
to have no sub-structure at all.
In the first case the organisation is clearly a commercial one, as it
is allocatged under the "COM" TLD. However, there is no information
as to the country the organisation is based in. In the third case,
we know that the organisation is based in France (FR), but without
studying the actual organisation name we do not know what type of
organisation it is. In the second case, we know the country that
both organisations are based in (UK), and by following the heirarchy,
we can deduce that the first is an academic organisation (AC), and
the second is commercial (CO).
While the system is flexible in not enforcing a strict heirarchy, it
can lead to exhaustion of domain names in the generic space and lead
to conflicts between organisations who may both have a legitimate
claim to have a particular name.

3. Possible solutions to name exhaustion
With such a flexible system, there are many ways of preventing the
name space being exhausted. A solution proposed by [2] is to create
more gTLDs to allow organisations with the same name to be registered
uniquely under different TLDs (FIRM, STORE, WEB, ARTS, REC, INFO and
NOM). However, this has several disadvantages as discussed below:
a) It creates confusion in users mind as to what TLD refers to a
particular organisation. For example, MCDONALDS.COM maybe the fast
food corporation and MCDONALDS.FIRM maybe a firm of lawyers, but
how is the user supposed to know which is which?
b) To prevent the above confusion, big corporations will simply
reserve all the different variations of the name, ie. IBM.COM,
IBM.FIRM, IBM.STORE etc. Thus we haven't solved the name
exhaustion or conflict problems, in fact we have made it worse.
c) Names of legitimate trade mark holders or other legally held names
can still be acquired by anybody, leading to potential conflicts.
Another set of possible solutions are discussed by The World
Intellectual Property Organisation [4] but this only addresses
dispute resolution when trademarks are used as domain names under
gTLDs, and not in the full legal context of their origin of
registration.
4. Proposed solution
With the aforementioned problems in mind, it is not a good idea to
create new gTLDs which merely overlap the existing ones. As the
domain name system is heirarchical it would seem a good idea to
expand on the existing structure rather than creating several
duplicate structures.
4.1 The world is not flat so why should domains be?
With the expansion of the Internet to a truly global medium, the
notion that there can only be one commercial entity, one orgnisation,
and one network provider etc. with the same name seems impossible.
This is the situation that the present system finds itself in. There
is a constantly spiralling number of disputes over who 'owns' or
'deserves' a certain name, with an increasing number ending in
unnecessary and costly legal action. This is not something that the
providers of a domain name service should concern themselves with,
but yet with the present system, this seems inevitable.
