IPv6 support on Virgin media
Does anyone know whether (and if so when) Virgin plan to implement IPv6 on its network?

IPv6 is just not a needed thing if a bank or game was to go IPv6 only then the roll out will happen.
I know of a way to double the current IPv4 (one IP shared by two) at the ISP end by MAC/IP/protocol/port learning and DHCP IP change on conflict that allows port/protocol forwarding because not everyone needs incoming so its likely that will happen first before IPv6 I think.
Xbox Live is IPv6 driven, since about 2013!
IPv6 is not needed as long as
A) Customers are happy being CGNAT and
B) Customers don't care about any new products or companies launching.
What you will see is that as new businesses launch from this point forward, there will be a delay before they get a lot of IPv4 addresses. Now, hosting providers have a lot of nifty ways of of getting the most out of a single IP, but it is going to be an issue for them. Not for the older internet players, but the new ones will struggle.
And I agree that there could be a fancy solution that allows automatic forwarding using something similar to UPnP to work with CGNat. That would be a complicated solution that would require something I haven't ever seen published. Why spend a lot of time and money doing that when there is a solution. IPv6...
With regard to CGNAT
Some of the companies that have now gone fully IPv6 looked at CGNAT solutions prior to implementing v6. They found it caused more problems than it solved, which is why they decided to roll out v6.
With regard to XBox Live
While it's true that they've been touting how they use IPv6 addresses to improve the multiplayer experience since 2013 - It's actually a weird state of offairs with them. Their IPv6 currently still relies on Teredo - in fact if you are on a native v6 connection and you disable Teredo - you get the lovely message:
Note: I'm at my parents in Inverness and using their BT connection, which is dual stacked.
If I turn Teredo back on
So ironically the IPv6 element of XBox live STILL relies on IPv4! 🤣 In fact if you are behind CGNAT then you get issues.
With regard to content providers:
Netflix has been dual stacked for some time now.
Facebook has been dual stacked for a number of years.
Google and hence Youtube has also been dual stacked.
Amazon is still IPv4 only, and if you dig microsoft.com you still only get v4 addresses.
