Granted, but it does seem risky to take as axiomatic that the Web is a
unified information space in which everything can be mapped, grounded upon a
system of network endpoints. The Web is not "designed as a universal space".
It happens to be a universal space for a particular information and network
construct, but it is (unfortunately) by no means all-embracing. It is a
universal space *only* to anyone with access to (one way or another) to an
IP address, not a DNS registration. Your DNS has to map to something if you
want to "appear" in that space.

Tim states that DNS is a tree with a single root. I can just about buy that,
as long as we are clear that the "root" is *not* the TLDs, as the sum of the
TLDs to do constitute a set. However, nothing prevents mapping multiple
(totally-unrelated) DNS addresses to the same "physical" IP address, so you
can/do already have multiple overlapping taxonomies mapping, as Tim actually
points out, within this space. When everyone with a .com, .edu, .mil, .org
or .gov DNS address moves to the .us or other ccTLD, then we might be able
to talk about a single root ;-) and even then...

Most people's concern, as Tim rightly states, is to have some "control" over
"their" information territory. But therein lies the problem, if such a
"territory" is defined as (and/or understood to mean) a DNS registration.
Several DNS gold rushes has come and gone (.com, .biz, .info), but there's
is far more gold in "them thar hills", if we keep inventing new hills to
mine. That should be a major concern: one can only claim something as one's
own, as "mine", if one can uniquivocally state at the same time also that it
is, by definition, not "yours". You can do that with IP (within the
constraints of DHCP, etc), but not with DNS. Just because I can state on
*my* map, for example, that some territory "is" the USA, or "is" a
trademarked brand-name, doesn't make it true. The map is *not* the

With overlapping information spaces (and I await with some trepidation to
see what finally comes out for the .eu domain, the internal politics of
which I have followed and are frankly hair-raising...), such a claim can
never be made without doubt or ambiguity.
