@Alex I don’t really understand the peer-to-peer thing. That is impossible with most domestic firewall-routers because (a) they are firewalls and (b) domestic unclueful users have NAT generally and (c) most users are clueless about networking and network architecture so couldn’t even configure things appropriately anyway if they had the capability.
Forgive my ignorance about this subject though because I have no experience in the area of this kind of software. My network is used for my wife’s business and security overrides everything, so firewalling is draconian. I have no IPv4 NAT, as I said, so the result is that IPv6 seems very like IPv4 to me.
For anyone considering the transition to IPv6, firstly why? Secondly if you want to do it, get you life clean, chuck out the bad kit and software, like ripping off a bandaid and it might be a useful step to transition to no-NAT IPv4 first, I don’t know. That might help sort your mind out.
I didn’t follow the point about VPNs. VPNs don’t care about IPv6 vs IPv4; lots of AA users have VPNs, I’m sure.
AA has one or two IPv6-only users. Now that’s hardcore. It’s something that AA supports. In such a case those users access the IPv4 internet still but by going through an IPv6 to IPv4 NAT64 translator at AA. The users’ hosts do this because their DNS64 service feeds them fake results to DNS lookups that result in IPv4 answers which point to the NAT64 translator instead, I have forgotten the details. See
https://tools.ietf.org/html/rfc6147I went IPv6 in 2010 because I wanted to learn. That meant throwing out routers and two ISPs: Demon (business) and Zen (at different sites). Zen got the boot because they kept on making pathetic excuses about IPv6, in response to my repeated nagging, otherwise I might still be using them. I chose AA because they were by far the most experienced IPv6 ISP around, having even back then run a fully IPv6 capable service for many years. They had spent years nagging BT about bugs that made IPv6 over PPP problematic (corruption of packets [!]) even though BT should have no idea what is inside a PPP PDU as it’s none of their business. But bugs are just bugs and sometimes happen without ‘design awareness’, just being triggered by what is the case in the data in an unusual situation rather than by evil intentional design, like treading on a rotten floorboard.
All modern web browsers prefer IPv6 over IPv4. Why this is is incomprehensible to me; it should be the other way around, since IPv4 is always faster
pari passu. They all now afaik use the ‘happy eyeballs’ algorithm which races the two IP networks against one another, and then records which is the fastest. It also by design detects ISPs with broken IPv6 and horrid IPv6 Teredo networks.
