In a special environment, having IPv6 enabled causes the first DNS query to fail. Any successive dns queries will succeed (first goes to ipv6, second to ipv4, then cache).

I certainly can't deny Derek's rationale though regarding not disabling and I'm curious to hear any thoughts from the early ipv6 adopter camp.

httpd 31611 root 8u sock 0,5 34880 can’t identify protocol

I think it was causing some memory issues for me but I’ll be able to say for sure tomorrow as I just disabled ipv6 and am letting it run for a bit. I certainly can’t deny Derek’s rationale though regarding not disabling and I’m curious to hear any thoughts from the early ipv6 adopter camp.

I have seen instances of SSH brute forcing through IPv6 in data centers. A remark for all IPv6 early adopters.

Why disable IPv6,when you need to start migrating to IPv6. I understand in one sense,that there is little native global IPv6 in some areas,but that is really no excuse. The way I see it,adoption of IPv6 will be as desirable for some,as learning the metric system. I agree with Mr. Morr.

If you don't start preparing for IPv6 now, you'll be in for a world of hurt when you have to start using it. It's better to prepare now, before it's a crisis.

You just want to do your job quick and right, so this is left to people who really need those features or do have enough time to test them well.

It shouldn't hurt anything to leave it enabled. And we'll need to migrate to IPv6 soon. The more people turn it off on devices, the harder it will be to get it deployed. Why?
