I think that "PTT" is the operative token here, but for reasons having
nothing to do with competition. If all they wanted was competition,
the easy answer would be to set up more registries -- or registrars
-- not bounded by geography; as long as the number wasn't too large, it
wouldn't do too much violence to the size of the routing tables.
If a PTT-like body is *the* registry for a country, and if the country
chose to require local ISPs and business to obtain address space from
it, what's the natural prefix announcement to the world? Right -- that
country's registry prefix, which means that all traffic to that country
just naturally flows through the PTT's routers and DPI boxes. And it
benefits everyone, right? It really cuts down on the number of prefixes
we have to worry about....
Until routing domains (i.e., ASNs) are carved up to become congruent
to national boundaries for national security, censorship or other
reasons. When this happens, not only will those IPv6 prefixes become
fragmented, so to will their legacy IPv4 space, and certainly to the
detriment of routing scalability, security, and stability.
Then add something like RPKI to the mix and you've got a very effective
hammer to enforce national policy - all network operators will use
the national RPKI trust anchor, and all of your address space will be
allocated (and certified) strictly from this national Internet registry
- so that they can surgically control precisely who can reach you, and who
you can reach - within the whole of the global routing system, and
DPI, tariffing, etc.. are all much akin to models of yester that they
can wrap their heads around.
And all the efforts and bottom-up policy driven by the RIRs in the
current model will dry up, as will the RIR revenue sources, and their
much wider contributions to the Internet community.
If you think the RIRs and the current model sucks, well, consider
the alternatives. For that matter, so to better the RIRs and their
It's funny -- just yesterday, I was telling my class that the
Internet's connectivity was not like the pre-deregulation telco model.
The latter had O(1) telco/country, with highly regulated
interconnections to anywhere else. The Internet grew up under the
radar, partly because of the deregulatory climate and partly because
especially in the early days, it wasn't facilities-based -- if you
wanted an international link to a peer or a branch office, you just
leased the circuit. The result was much richer connectivity than in
the telco world, and -- in some sense -- less "order". Syria wants to
roll the clock back.
I can't believe that the current model of more dense interconnection,
continued disintermediation, and a far more robust IP fabric would
evolve to be more resilient and robust from national Internet registry
allocation models or the Internet routing system rearchitecting that's
sure to follow.
Of course, if the ITU-T is serious about this, they should probably be
asking for a good chunk of 32-bit ASNs as well, but that's a bit more
difficult to do under the auspices of liberating IPv6.
