It has finally happened: There’s no more IPv4 addresses left to allocate, at least for ARIN – and that’s going to affect most people reading this. Ask your ISP for IPv6 access. The next step is being forced to implement either wonky 6to4 mappings, or just plain IPv6 networks.

Yes it’s time:
$ host dragonflydigest.com
dragonflydigest.com has address 67.242.210.97
Where’s yours btw?
I had a tunnel running for a while through Hurricane Electric’s service, but it was extremely difficult to keep working. I don’t know if it was DragonFly’s IPv6 tools, my misconfiguration of the tunnel, or a combination of both.
Either way, my ISP (Time Warner Cable) does not yet offer IPv6 as part of its network, and I wish they would.
Many providers have lots of ranges routed to old dial-up modem banks and otherwise used wastefully.
And thats the low hanging fruit!
The sheer cost of ipv6 (and lack of immediate benefits) will almost certainly drive programs for internal efficiently for at least another 5 – 10 years.
Well, I have no problem with IPv6 at home. My DOCSIS connection has a IPv6 native /56 and a native IPv4, so that I have a real dualstack. Before, with another provider I had a DS_Lite with one /64 and CarrierNATed IPv4.
But that is Germany. In Slovakia I still have no IPv6 natively. I am using DSL there with a real IPv4 and go over HEnet 6in4 tunnel into IPv6 network, that works great. I even have a /48 there, so that I can do hints on it, like 1113 for the houses 11 and 13 and the 2000 for the house number 20 on the other side (another street). That’s cool!
With providers it is worse, because some hosting providers, mainly those who do virtual KVM vservers, are filtering the multicasts according to some rules that brake the implementations of BSDs for example. That’s for example that a router forwards only over global IPv6 but is reachable only over link-local IPv6. And when a BSD OS is trying to do a combination of both, wanting to go out, it fails miserably.
My ISP gives me a dynamic v4 address (static if I wanted to pay for that). There is therefore no benefit and definite cost to changing, so I won’t. I suspect many organizations have come to the same conclusion, so its no big surprise to me that adoption has been poor. Had IPv6 been a slight modification to v4, rather than a complete change, maybe things would be diffferent.
I do not aggree here with corey, for me IPv6 is a big step forward, and I am not prepared to live without it any more. The good message here is that now more than ever ppl will have to adjust to me and not other way around. Even though, that never happened. LOL!
