I respectfully disagree, at least in part.

I probably should have said, in the first place, that if there are
multiple roots, they need to be authoritative. One can envision a number
of ways for that to be implemented - most of which would seem to require a
human arbiter to settle disputes (if not ICANN, then some other body).

I would suggest that telephone books/directories are not an appropriate
analogy. Rather, DNS is a lot closer to the internal plumbing of the net -
more akin to Signalling System #7. I'd guess that for 95% or more of phone
calls, the caller already knows the numeric phone number in question -
while for the Internet, very few people give their email addresses as
mfidelman at 207.226.172.79 or http://207.226.172.79. Telephone directories
are optional in most cases, DNS is not.
Yes, the Internet can function on
numeric IP addresses alone - but unlike the phone network, people don't
give out email addresses or URLs containing their numeric host addresses.
Regarding the rest of Karl's article, talking aout a completely open world
of multiple root servers. I am simply reminded of the days when we had
rapid additions to the range of area codes an local exchanges. I remember
numerous times when I could not make a call from a company's PBX - because
that PBX's software hadn't been updated, and didn't recognize the validity
of some new area code or exchange. I've also encountered this problem with
software not recognizing new zip codes.
At least with phone numbers and zip codes, we don't have the problem of
overlapping namespaces - there are clearly established legal and
regulatory authorities that manage the telephone numbering and postal code
namespaces.
I suggest that there are three very specific problems that need to be
addressed:
- propagation of new namespace information
- uniqueness of namespace information.
- avoiding namespace hijacking
As long as there is a single set of root nameservers, run by a single,
accountable organization, these are easy problems. As soon as one admits
of multiple root servers, the following problems have to be addressed:
- the operational problems of dealing with incomplete propogation of
information (particularly when dealing with the clueless: "what do you
mean you can't find my web site, I registered it with new.net")
- an official way to deal with conflicts between overlapping top level
domains (dealing with the trademark issues is bad enough, but where does
someone go to fight out ownership of "good.sex" when 100s of different
people register it with competing registrars) -- I'm not saying we can't
come up with an arbitration scheme and somebody with the clout to
enforce decisions, just that one will be needed. In the current system, as
with phone numbers and area codes, there simply is no way that the same
domain can be assigned to multiple people.
- a similarly offical mechanism for dealing with conflicts when different
registrars, above board or otherwise, provide different information for
the same domain
In other words, we need an authorized international body with the clout to
oversee the whole mess. But then, isn't that what ICANN is supposed to be?
(Or would you rather have the ITU oversee the Internet?)
Speaking as someone who hosts a whole bunch of web sites and web sites,
I see a world of profit-motivated, competing rootservers as creating an
incredible number of problems that I'd just as soon not have to deal with.
