Re: @AC - starting to see malware attacks in IPv6
I've had two cable ISPs that supported IPv6, now. Every home router I've used that had IPv6 had a firewall turned on by default. My cell phone provider also uses IPv6, BTW, with IPv4 support behind carrier NAT.
NAT was never supposed to be a security barrier; that it functions as one is mostly by accident, because it happens to require a firewall.
I've had no problems except for once early on when Comcast turned up IPv6 locally before they were ready to route it. A substantial fraction of my web and video streaming traffic goes over IPv6 now, and I can't say I notice a difference. And that may be part of the problem; for the consumer this isn't really a value-added proposition.
