30% in the UK
So depressing that this is a tech website and the forum section on any IPv6 articles are full of comments about how different, wrong, funny-looking, new, scary etc IPv6 is.
Often people say something like "IPv6 is 25 years old and still crap" then no follow-up or technical justification of their opinion. Probably voted for Brexit.
Sometimes people reel off one of these:
- "IPv4 had better features" (then claim NAT is a feature)
- "But my IoT will be publicly addressable" (noone cares what random address your TV got out of the grains-of-sand-on-earth's worth that your ISP delegated to you. Your ISP gave you a box which does the same job with IPv6 as it did with IPv4)
- "But they can track my pr0n" (lol as if your v4 address in a residential ISP pool and browser user-agent isn't all up in pr0n trackers already)
- "But Android doesn't support DHCPv6" (ok, sure, you need to push out vendor-class options or PXE boot your Android device)
However people waffling away in forums and tech websites dissing some technology they don't want to learn are not the point.
IPv6 will keep being deployed to end-user networks regardless of whether `COBOLSL4Y3R` in some forum thinks it's crap for... reasons.
If you're a recent fixed-line subscriber to BT/PussNet or Sky in the UK in the last couple of years, you likely already have IPv6 enabled and it just works.
Mobile networks in the UK are a long way behind US, Europe, Asia, but I've been roaming, tethering, all of it, with IPv6 on mobile and it just works.
I'd be extremely surprised if there's an end-user ISP or mobile provider in the UK that isn't piloting or actively deploying IPv6, if not deployed already. In fact I'd welcome anyone naming any UK ISPs that are categorically saying they will never deploy IPv6.
If you're running servers in an enterprise, small biz, hosting provider, public cloud or your own shite-cloud and happy with v4 NAT to RFC 1918... then fine. Leave it. Noone will care about your dreadful Citrix/Exchange/whatever being v4-only anyway.
Is IPv6 perfect? No. It's different. Read about it. Learn all of it. Deploy it.
IPv6 will keep rolling out to end-user networks over time regardless of whether you like it or not.
Crying in a forum and waiting for IPv4-ng is just pointless my friends.
