Free IPv6 Subnets Are Going Away
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.
You can get free IPv6 subnets using the much more efficient 6to4. 6bone isn't needed any more; that's why it's being phased out.
New addresses can be allocated until July 1, 2004.
Existing addresses can be used until July 1, 2006.
the 6bone network was a TEST NETWORK, if you didn't fully expect this TEST NETWORK to go away after a while, you are just plain delusional.
Here's the relevant text, snipped from the TOP of the memo (i.e. you didn't even have to read MUCH of it.)
The 6bone was established in 1996 by the IETF as an IPv6 Testbed network to enable various IPv6 testing as well as to assist in the transitioning of IPv6 into the Internet. It operates under the IPv6 address allocation 3FFE::/16 from RFC 2471. As IPv6 is beginning its production deployment it is appropriate to plan for the phaseout of the 6bone.
So, please, please, PLEASE stop complaining about something that was supposed to be going away from the very beginning!!!
- A.P.
"Remember when the U.S. had a drug problem, and then we declared a War On Drugs, and now you can't buy drugs anymore?"
refer to RFC 2471, which established the current address allocation: "These addresses are temporary and will be reclaimed in the future."
And why are they closing the 6bone? "As IPv6 is beginning its production deployment it is appropriate to plan for the phaseout of the 6bone."
They're just cleaning up from the testing phase so they can move into official use. It's only a step backwards if you consider the end of a beta test a step backwards.
Yes 6bone itself is going away, which means the 3ffe::/16 address allocation is going to be reclaimed down the road. What this means is tunnel brokers like freenet6 are just going to need to get a new address allocation. There are a number of tunnel brokers already using other addresses, mainly under 2001::/16. So for all the posters who are going all doom and gloom, get a clue, wait, this is slashdot.
I wish people would *read* the articles first and *understand* what they mean before blathering on about them.

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.
/20 as of 1998 i believe it was)
/20 or more, you are suppost to buy the block from ARIN directly.
:)
/24 of theirs on its own ASN, and tell the other ISPs you use to route over the whole block. /28 out of that, your more than welcome to. /24, it would be more wasteful to leave them unused than to simply route them to you in the first place.
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
If you need 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
If you want to subnet just a
But as the ISP cant use any of the other IPs in that
I don't think you know what you're talking about.
The IPv6 protocol declares that extension options are end-to-end, meaning that in-between nodes do NOT look at any of the options headers. The ONLY exceptions are the Hop-by-Hop option header, the Routing header, and the Destination options header.
Packet fragmentation and reassembly are ONLY done by the source and destination nodes. (Yes, the underlying link may do fragmentation, but that is entirely the problem of the layer below, IPv6 does not care...) The IPv6 header area - which includes the Hop-by-Hop header, Destination options, and Routing headers, if present - is considered UNFRAGMENTABLE.
You need to re-read RFC 2460.

Currently the internet uses IP protocal version 4. Version 6 is supposed to fix some of the problems of ipv4. Notable among these is the larger address space (128 bits instead of 32... actually I seem to recall that this may also have changed in the spec to an expandable scheme(?)), and things like QoS.
The biggest problem is that none of the primary routers support it. Network providers aren't interested in the expense and difficulty of upgrading, and hence aren't buying the new equipment and software required. Others are waiting for the equipment and software to become more common. In turn, product and software manufacturers aren't terribly interested in it until they get orders. Others are waiting for everyone else to use it (and be the Guinea pigs).
A "chicken and egg" situation.
The Internet has some serious problems that need fixing, but it also has way too much inertia to allow change to occur.
Guys, there are a lot of misconceptions about IPv6. I appreciate this - it's not an intuitive subject, and it's possible to believe you know a lot more about it than you actually do. But, the details are there. Please do the reading and start asking your ISP for connectivity. No, your real ISP. There are people out there who want to deploy this, now, and we're waiting for customer demand. Go nuts!

Note that any single IPv4 address can be used to claim a /48 -- that's 80 bits of address space -- of IPv6 address space by sticking 2002: in front of it, e.g. 192.0.2.69 -> 2002:c000:0245::/48. This is called 6to4; see RFC 3056.
