Improving the situation

You are in a car, driving 60 miles per hour, trying to get to Canada.

You pass through Kansas.

You are driving south.

If you don't understand the problem I'm describing, look at a map.

Now how do you think you should solve this problem?

One might suggest that changing your speed to 30 miles per hour would be an improvement.

Do you agree? I doubt it. I bet most people reading this web site would think that the situation isn't getting better until the car is driving the other direction.

Why do I bring this up?

You've heard that the internet is running out of IP addresses, right? The last few blocks have been allocated and recycling has begun. You think that aggressive use of NAT and "carrier grade NAT" will save you. No, that's slowing down.

It's time to deploy IPv6. Really.

Turn the car around.

Sincerely, Tom

P.S. Both LOPSA Conferences (Cascadia and PICC) have an excellent IPv6 training class. Have you registered yet? Cascadia is in Seattle; PICC is in New Jersey.

I knew, I knew that! Canada is the ultimate place of peace and happiness!

Might I ever so humbly suggest that you use positive reinforcement rather than negative? That is, rather than continuing to tell us "stop using IPv4," I'm betting your message will be much more effective if you tell us "look how easy it is to switch to IPv6; here are some great resources to get you started."

All the best,

No, no, no! If we move to IPv6 the Gray Goo will win!

That's my next article. I just had to use this left-over analogy somewhere.

Hmmmm.

WTF?

remaker:
I have a bug opened with my ISP about that. My main site, jughandle.whatexit.org is definitely IPv6 capable!

The problem is that you can't just switch directions like turning a car around, you (somehow) need to drive in both directions until you reach the destination. This is the flaw in ipv6 - even if your office and ISP is 100% ipv6 working, you can't switch off ipv4 without shutting yourself off from the rest of the ipv4 internet, because there is no interoperability between the two. I really don't know what they were thinking. Furthermore, the job of converting every router, switch, server, applications, etc to ipv6 will take many, many years, whilst in the meantime users will still need ipv4 addresses to be able to remain connected, until the very last ipv4 device is switched off. I really don't know what they were thinking when they proposed ipv6.
