Free IPv6 Subnets Are Going Away

      For those wondering what the hell 6to4 is when it's at home, here's a brief explanation.

      the /16 prefix 0x2002:: is reserved for 6to4 tunnelling (so it's not something that IANA is going to reclaim any time soon, any more than they're going to reclaim 172.16/12...). A 6to4 TLA is 48 bits in length, and comprises 2002:(your gateway IPv4 address in hex.) For instance, the 6to4 prefix at work, when I was playing with it, was 2002:CB53:9C82: (as the IP I was using was 203.94.156.130.)

      For those unfamiliar with how IPv6 addressing works, under a /48, you have a network space the size of a /16, each of which is its own /64. ie, under 2002:CB53:9C82::, the subnets would be 2002:CB53:9C82::/64 through 2002:CB53:9C82:FFFF/64.

      Each subnet can host up to a /48 of machines, the other half of the address is the Layer 2 address of the endpoint machine passed through an algorithm to convert it to 64 bits in length (forget the RFC which specifies this.)

      The advantage of this setup is that ingress traffic doesn't need to pass through a series of tunnelled networks, as the endpoint address is encoded in the prefix.

      Outbound traffic still passes through a gateway of some nature, which will then figure out how to dispatch the traffic (eg it could be connected to the 6bone, some native 6nets, or the destination address could be another 6to4 address.)

      FreeBSD has a good 6to4 implementation called stf(4). I recommend checking it out if you're curious :)

    ARIN is the reason there are no more IP addresses.

I know you got more because they can't dish out any less than /22 or so now.

    I think that ARIN should start a policy that for any new allocation, 1/16 must be dual homeable. These addresses would be dual allocated to two ISPs at the same time and that any large ISP that needs more address space must set up agreements with other ISPs. This would force them to change from the model they use now to one with more cooperation.

    You do realize that you can get a block of IPs from one of your ISPs, and if they are willing, they will SWIP it to you, assign you an ASN, and you can do BGP between the main ISP (that the IPs belong to) and any other ISP that will do BGP with you.
    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 /20 as of 1998 i believe it was)

    If you need a /20 or more, you are suppost to buy the block from ARIN directly.
    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 /24 of theirs on its own ASN, and tell the other ISPs you use to route over the whole block.
    If you want to subnet just a /28 out of that, your more than welcome to.
    But as the ISP cant use any of the other IPs in that /24, it would be more wasteful to leave them unused than to simply route them to you in the first place.

    ON TOPIC: It reminds me when I was a kid and our neighborhood was being built over a period of several years. 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. If enough people have allocations, and someone tries to take them away, the ballot box might even come into play.

    This isn't the place to go into details, but it's designed and planned to run concurrently with IPv4. This isn't like the NCP/TCP change over where there was a huge redflag day for all 200 hosts on the Arpa net.
    Everything in my house speaks IPv6 except a printer and a terminal server (you do all have terminal servers for those serial toys, yes?). Those will never be upgraded - too old. When I ssh, mail or browse, if they have a 6 address and I can reach it, it gets used. Otherwise it falls back to IPv4.

    At work, if you have a subnet with all IPv6, you can turn off IPv4 and let your edge gateway it. But you may not be turning off all the IPv4 until that last printer dies. Do it subnet by subnet and leave IPv4, but just watch it not be used.

This would slow them down tremendously and cause them to fail to hit most of the vulnerable machines. In contrast, Code Red managed to get behind firewalls in many companies.
