<p><font size="4">1) " ... upgrade every major legacy router in

EzIP approach starts from deploying RANs (Regional Area Network)

Internet core via one IPv4 address as the umbilical cord. With
this architecture, RANs form an <i><b>overlay</b></i> to the
existing Internet to provide equivalent services in parallel. It
will start small and individual locally, then grow bigger by
interconnecting through compatible RANs. There is no need for
reprogramming existing Internet routers, although doing so will
expedite the EzIP deployment. This concept is one step beyond
just making use of 240/4 netblock as another unicast IPv4
address pool. So, the consequences are quite different. Hope
this clarifies the issue.</font></p>

I don't think even the authors of any of the proposals really believe
this type of thing would be possible, upgrade every major legacy router
in the world. And if 240/4 would make it to a state it can be used it
could still well be used for example inside a backbone in a regional way
that allow many organizations to move those more 'noble addresses' to be
used as Global ones, IXs, Interconections, etc.
I also don't see if that would happen one day people would just "stop
deploying IPv6" until the issue of IPv4 exhaustion "comes back again".
That just doesn't make any sense.

<pre class="moz-quote-pre" wrap="">Hi, just adding a few words to the Tomas Lynch comment.
Please, don?t forget that the Internet infrastructure is not only the
part created by a few big operators and Tier I or II ISPs. The
Internet is really bigger than that. If you make a real-time inventory
now, you'll find that there are a lot of working devices on the
Internet that have reached their end of support from their respective
manufacturers. Of course, those devices won?t be upgraded to scale to
the new ExIP but they'll keep up and running. It will be an unwanted
situation for the operation and the stability of the Internet
infrastructure.
Doing this kind of ?fix?, you?ll have to make almost the same effort
(inventory, software patching, hardware upgrade and replace, routing,
security, and so on ) that deploying IPv6. Recovering this /4 block
might allow a 2-4 years of ?peace? but after that we'll be in the same
situation of IPv4 exhausting that we have nowadays. Definitely, to
adopt ExIP, we?ll have to invest a lot of efforts and money in a
temporary solution instead of a definitive solution for the same price
(or less, because even when a lot of operators haven?t deployed IPv6
now, they have been acquiring IPv6 capable hardware and software as
part of their usual business process). Deploying IPv6 is the
definitive answer.

Jorge
