Ipv6 readiness

Posted 03-10-2012 at 11:03 PM by Skaperen

Ipv6 is coming. Are you ready for it?

I have no idea when IPv4 exhaustion will reach the point where you have to use IPv6. You have IPv4 now, and no doubt virtually all ISPs will keep people on IPv4 in some way (even if they have to use NAT) much like cable TV companies are providing at least some means for analog TVs to work (with boxes as the convert their TV systems over to all digital). So YOU may think you won't need access to IPv6 for a while.

But I suspect that IPv6 will be kind of like the internet was in the early days before all those business marketing people discovered it. I suspect some sites will intentionally provide more open access to anyone reaching them over IPv6 because IPv6 will be, at least for a while, an IQ filter.

Linux is mostly IPv6 ready. It's a major platform IPv6 was developed for in the previous millennium (yeah, it started back then). But I have seen some glitches, not so much in the form of bugs, but in the form of "issues". For example something called "proxy NDP" which is the v6 equivalent of "proxy ARP" (a way to effectively route certain addresses on LANs where normal routing is not practical), does not really work as well. It can be made to work. It's not a bug, although the difficulties may be due to an issue with the design of NDP (IPv6's ARP).

That's why I'm doing IPv6 already (have been for the past couple years). As a system/network administrator and programmer, I should be ready for it. I really should have been ready years ago. Working out the glitches and rough patches is part of what prepares us.

Now I wonder when LQ will be reachable through IPv6. Can you guess what the first issue is that LQ should consider, and why it should not just up and turn on the AAAA record immediately?
