Clearwire forcing NAT on customers

Wireless Networking 6

Clearwire is rolling out WiMAX in the Seattle area, and that comes with new modems that force you to use NAT. They aren't giving their customers public IP addresses at all. This makes running IPSEC based VPNs or 6to4 tunnels over Clearwire next to impossible, and I consider Internet service that only comes with non-publicly routeable IP addre

Welcome to Carrier Grade NAT (1)

IPv6 failed and IPv4 is out of IP's. Welcome to Carrier Grade NAT.

In point of fact, IPv6 hasn't failed. I know of at least one major consumer-level carrier who is planning trials of IPv6 in the next couple of years.

From your second sentence I would draw exactly the opposite conclusion than your first sentence.

How do you figure?

You know of one major consumer-level carrier who is planning trials within the next couple of years. Meanwhile we're 2 years from address exhaustion on IPv4.

At this point IPv6 should have been available everywhere. Practically no one has native IPv6 available. Very few carriers are running trials. They all have vague plans for trials over the next few years, but that's about it.

IPv6 is still not in the base license on a lot of core Cisco gear.

The game is over and Carrier Grade Nat won.

I disagree. The signs I see show that IPv6 adoption will happen just in time for address exhaustion. IMHO, that's about 2 years too late, and will cause a number of difficult problems. But it will happen.

I have seen a very notable uptick in the amount of activity surrounding IPv6 adoption in the past 6 months even. My DNS provider now tells me that they have plans to implement IPv6 glue records. My ISPs tech support people know what IPv6 is and claim there are plans. This wasn't the case a year ago.
