IPv6 Only, drawbacks and work arounds?

(1/5) > >>

AnthonyG:
I was just thinking to myself. My future ISP offers IPv4 over CGNAT and IPv6.

I was just thinking therefore. If someone was to (try and) go entirely IPv6 only. What would be the potential drawbacks with them doing this? And are there any work arounds for it if they exist.

As in just disabling IPv4 entirely in the router (if that is possible) and just having IPv6 so I don't have to bother with CGNAT at all.

If I was to try and do this my only uses would be regular browsing the internet, streaming on the likes of Youtube, Amazon Prime TV and Netflix and playing Call of Duty on Xbox Live on the SeriesX.

Would this be possible through IPv6 only and if not are there any work arounds to get the above to work?

It just seems if the future is IPv6 I may as well try and be the first on board.

Alex Atkin UK:
You could totally go IPv6 only, but without a 6to4 translation at some point a LOT of websites plain wouldn't work any more.

This is the exact problem with IPv6 - support is still poor overall hence being first gets you (literally) nowhere

Alex Atkin UK:
My friend in Texas, AT&T relatively recently "upgraded" his connection to dual-stack.  After the 5000th engineer visit, they disabled IPv6 in his router as their platform had been super flaky.

So if even an ISP is choosing to selectively roll it back for individual customers, we have no hope of it ever becoming the default.

Weaver:
I couldn’t disagree with Alex more. Imho it already is the default and end users don’t realise it. All modern web browser and some other applications prefer IPv6 by design and the ‘happy eyeballs’ algorithm in eg web browsers is used to check for a rubbish IPv6 connection such as a bad teredo one by racing IPv6 and IPv4 against one another. I’ve been using IPv6 consistently such 2010 with zero problems. World IPv6 Day was back in 2012, and then it was that all massive internet companies the likes of Facebook, Google et al agreed to switch over to offering IPv6, so because of Web browsers’ preference algorithm, a huge slice of all traffic instantly went IPv6 where users had capable ISPs, simply because of the dominance of a few large companies in terms of users’ traffic. Alex is right if thinking about counting webservers rather than fraction of total internet traffic. As far as I can see. in the UK, total IPv6 traffic is still quite a bit less than the volume of IPv4 traffic, according to the stats I’ve seen from the London internet exchange LINX.

AA does offer zero-IPv4 service with full access to IPv4-only machines such as web servers by using DNS64 + NAT64 kit in their network. It’s not true in this case what the earlier poster wrote about losing access to the huge slice of the web because if the high number of IPv4-only web server. How it works is that the networking kit at AA lies to the user’s machine in the DNS64 address lookup responses and in the case of an address lookup that returns only IPv4 results, the responses are faked to give out a reset that is the IPv6 address of AA’s NAT64 translator server. Then IPv6 traffic destined supposedly for say some web site that is in fact IPv4-only goes through the NAT64 translator and the packet headers are rewritten making it into IPv4 with dest address being the actual destination machine and the source address being that of the NAT64 translator, not the original sending machine. This is done to ensure that replies get sent back to the translator which in turn rewrites the headers translating in the reverse direction according to its inverse mapping tables set up in NAT. The process is indeed analogous to the IPv4 NAT algorithms that you may already be familiar with, just rather more radical. You can read about this on AA’s website at https://support.aa.net.uk/IPv6_Only.
