Just send them a bill for a reasonable amount, say $500 or so. They will know they did something wrong and will either pay or rectify. Stay courteous and don't threaten legal action of the bat. You're likely to make some money.

yet another article that's skeptical of how ready IPv6 is. The amount of brokenness that is there is not very big. Of all the people that have the full Internet (that is IPv4 *and* IPv6) most will simply connect to any IPv6 website without issues.

And apart from the fact that yahoo seems to be a US only thing, and even there is not so relevant anymore, I applaud them doing IPv6, when they get to it. (and after Google, Comcast, Akamai and many others)

I wish we'd get over this "brokenness" story and simply deploy and then fix it for the 1% that has issues. Would be nice if it gets rolled out to the point of 20% traffic in 2011, the year we'll run out of available IPv4 addresses.

Skype is popular because it can function even when both ends of the conversation are going through a NAT. NATs are inherently evil (no, they don't offer more protection than a simple ingress filter on any "real" router) and break the end-to-end principle. With IPv6, you will not get just 1 IP address like in IPv4, but a shitload (currently the thinking is a /48, which is over 65000 subnets, each subnet containing roughly 4 billion * 4 billion addresses, but thinking is changing towards /56's, only 256 subnets, still an impressive number of addresses).

What this will do it 2 things:

1- allow for more machines to do any particular service. (multiple VoIP devices, multiple webservers, no extra configuration to restore ICQ file transfers, easy webcamming)

2- reduce worm problems (because most addresses are not used, simply scanning address ranges will not be successful, limiting worm propagation by several orders of magnitude)

So, no, it doesn't remove the need for servers per se, but most applications that set up peer to peer connections these days need some other machine to bypass the NAT problem. With IPv6, NAT is no longer needed (although there will be idiots that think it makes things more secure and demand it for IPv6 as well. I'm praying it won't catch on)
