[c-nsp] OT : IPv6 - Will it hit like an "avalanch"?

Wed Apr 2 09:29:13 EDT 2008

I want to set an appointment with you in, let's say 10 years from today and we can talk it over again…
Do you know how many of the IPv4 "allocated" addresses aren't actually in use and are only held at the LIRs and RIRs IP "storage basement" for future use?
This could happen in the future too, a single person can apply for a million IPv6 addresses and perhaps he will get them, because "there are som many, so what the heck, let him have 'em…"
We'll see, I hope I'm wrong…

Nah

They really over-engineered the IPv6 address space

Its something like only 25% of the IPv6 address space gives you 100 IPv6 addresses per nanometer of the surface of planet Earth.

When did exactly the IPv4 started? Did they ever think about the day the 4294967296 ip addresses won't be enough for the world?
I think it's the same story with the IPv6, today we talk about the much more IPs we're going to get, but it will be so many that in a short term every little thing will have IP capability, so, every toaster, every refrigerator, every RC Car, every cellphone, pencils, bike, car, and so on, all of them, EVERYONE will get a unique IP address, and that's it, we'll be at the same exhausting problem shortly, much sooner than you can imagine...

It is well understood now that IPv6 really has nothing to do
with solving DFZ table bloat.

That renumbering would be a snap is only true if you
ignore real-world issues like DNS, firewalls, ACL's, etc.
You can only push ULA addressing so far and we'll be
back to NATing IPv6.

I've best heard IPv6 described as "96 more bits, no magic".

The IRTF RRG has been exploring this problem space.
