Free IPv6 Subnets Are Going Away 182
ar32h writes "The 6bone is going to be phased out soon.
This means all of us who have IP addresses or subnets beginning with 3ffe from tunnel brokers like Freenet6 are going to be sorry out of luck." According to the linked phaseout plan, "It is anticipated that under this phaseout plan the 6bone will cease to operate by July 1, 2006, with all 6bone prefixes fully reclaimed by the IANA," but there are a number of sub-deadlines along the way.

It wasn't one of those circuit neighborhoods where they develop three floor plans and build 1000 identical homes. This was a neighborhood where you bought the land and were then responsible for buying your own floorplan and/or hiring an architect to design or modify one for you. We had lived there for a number of years, and during that time, my friends and I had turned some abandoned lots, still covered with trees "in the wild", into our "clubhouse." It was really cool. We had put together these cheezy, sloppy little shacks with all kinds of construction leftovers from other parts of the neighborhood, like 2x4s and pieces of thrown away plywood. It was probably dangerous--these things could have toppled over on our heads because they certainly weren't nailed in place. But we were kids, so who cared? There was even a small crater where a four-seater airplane crashed some years before, and that was our "punishment hole." If all the kids voted that one of the kids was a troublemaker or a bully or something, then when that kid came outside to play, he had to sit in that pit all day without being allowed to play with the rest of us, and this had to go on for a specified number of days. (Nobody ever got sentenced to that punishment though.) It was really cool, and this went on for a number of years. One day, we go to our "clubhouse" to find that all our stuff was taken down and there was a big bulldozer knocking over all the wild foliage. They had already taken down a few of the trees and were in the process of clearing the rest of the land to begin construction of a house. Of course, I was a kid and didn't understand these concepts, so I remember running home to my parents and yelling that someone was tearing down our clubhouse! They explained that this land had belonged to someone throughout all the years that we had used it as a clubhouse but they just now got around to developing it. So how come we were being kicked out, I asked... My parents said, "You should be happy that they let you use that land for all this time, instead of complaining that you're being kicked out!"

Each person on earth gets allocated around 10^20 addresses for their personal use. Allocation could be done by setting up a web site and having a script that keeps track of enough details to uniquely identify a person and allocating them an address block. It will be up to each person to honour others' address allocations and keep to their own turf. Given that each person can easily get 10^20 addresses of their own, hopefully the incentive to invade other people's address space will be small. As new people are born, parents can divide their family pool among their children. 10^20 addresses should see even the most active couple out for quite a few generations.
IANA can have fun assigning the rest of the (10^38-10^30 = a big number) addresses.
If IANA don't like this, they can go and make a running jump. As long as enough people participate in the scheme (and the network is decentralised enough) it will work.
NOW is the time to do this! One does not need the network to be implemented to allocate addresses!. If by the time IPv6 hit the streets a few tens of millions of people have personal address spaces allocated, it will be difficult to demand that IANA be the sole issuing authority.

Some bright spark had this notion of packet switching, and it caught on. It's like this - once you deploy the packet switching network, the telco is no longer the arbiter of what applications are run on it. You are. You can run a mail server, I can run NNTP, and some maniac over there is writing something called a Web Browser.
The innovation that made the internet what we know today came from the fact that any idiot could develop a protocol, not just a telco engineer.
Now, cut forward. We have an internet, but we're kind of short of address space, so we use a lot of NATs to conserve them. What's going on here? Well, I can use a sensible TCP application, but that's about it. If I want to run some crazy app that needs Multicast, or an instant messenger, or something that just doesn't get on with the TCP congestion algorithm - well, not only do I need the permission of my network security team (which is good and proper) - but I need support from the NAT box.
The NAT box needs to support my protocol, which might not even exist yet. You want to talk about chicken and egg?
And innovation stops. There's a lot of talk of the end-to-end principle and handwaving and that, but that's the meaning - there's no more innovation.
NAT is not a security policy. It's a means to conserve addresses. It has an added feature that prevents you connecting directly inward to hosts on the network - but so does a stateful firewall. The point of compromise is exactly the same. It's rude to use global IP space behind a firewall like that in IPv4 land, but only for purposes of conservation. In IPv6, that doesn't apply.

Even if your link to the main ISP goes away, your IPs that belong to them will still route through the other ISPs you have connections to.
This is how you are suppost to get IP space and multihome for small blocks of IPs. (Small being under a

In their contract, it actually states you have a years time to renumber your networks and give the ISPs IP space back to them, and use only your ARIN space. If you dont give the ISPs space back, you are in voilation of your contract.
But the whole reason that is there is because getting an ARIN block of IPs is an upgrade path from your large block of ISP IPs.
Both can still do BGP just the same.
Also to get an ARIN block, you must be multihomed already. That in itself should tell you you can multihome without their help
The main problem is, alot of routers are configured to ignore routes smaller than a C class (/24) so if you got less than that, they cant garentee all backbones over the world will have routing table entrys for their customers/transiant trafic to find your network.
Any backbone that used such filters would never route traffic to you, either from their customers, or from anyone that has to route packets through them.
Backbones do this because they do not want to buy memory for lots of routers. This has nothing to do with ARIN.
Some nicer ISPs will still do BGP with you on very small blocks of IPs, but as a large chunk of the net wont see you.
The only way to solve this is for the main ISP to mark a whole

Look, I'm not on a Windows machine, but a 5 second google search gives me MS IPv6 FAQ [microsoft.com] as the first hit. Microsoft are even running a 6to4 tunnel at 6to4.ipv6.microsoft.com.
Mac OS X 10.2 also supports ipv6 and can be enabled with 2 lines in the terminal. I'm not sure, but I think it is safe to say that all free Unices also support ipv6.
So basically, you have absolutely no
