The current problem with DNS is not load on root NSes
(however, even a blind person can see how exponential
growth at more-than Moore's law will get it to the
point where you simply won't be able to find a box
fast enough to run root NS). Those of us with longer
memories remember times when 16Mb on AGSes was "more
than enough for any foreseeable future". And, yes,
followinmg your analogy, 99.999% of routers do not have
to have more than 100 routes in them. Does it help
a dozen of dying backbone boxes much?
The current problem is increased name collisions. Which is,
to say, a fundamental one.
No matter how you jump you won't be able to decrease rate
of name collisions w/o increasing depth of the tree.
The only other remedy is to stop choosing natural
abbreviations and start doing as AOL does with customer
names. Which is, essentially, an inferior way to do
exactly what i proposed to do.
(And, BTW, there's life after 26 letters are done with;
you can set moving "line in the sand" on who gets shorter
But -- the idea that first level domains are sexy got
to be stomped out before anything real can be done about
New TLDs is merely moving the problem one level higher.
It definitely cannot fix anything.
PS. No, i don't call to "rename Internet". I call to
stop the insane practice of building the flat

Creating a problem to solve a problem is not a solution.
Paul already said that a 16MB 486 can handle root DNS just fine.
This does not bespeak of a problem requiring "renumbering"
hundreds of thousands of domains.
FURTHER, your "big win" is only a 1/26 lessening of load.
If the problem is such that 1/26 is a "big win" I think
it's not big enough to rename the Internet for.

No, it's not the same problem as routing. All routers with
non-default rules need to know about all routes. The only
possible analogy for that in DNS is root nameservers. These
(as Paul pointed out in a previous post, since he runs F)
are not saturated, and don't require that many resources.
If you feel the growth of domain names is such that it will
outstrip a 486 w/16MB soon, tell me when it will be a
SIGNIFICANT problem. I.e. when will it outstrip a real
machine (Sun, VAX, Alpha, SGI) with real memory (64MB?
Remember, upgrading HUNDREDS of routers all running 45Mbps
is a priority. Upgrading 8 boxes running BIND and doing
it well is a much much much lower priority.
