So there is no real benefit for us in the UK at the moment?
I've seen some info about ipv6 being put into ipv4 packets.
The reason i ask about ipv6 is i play Xbox and i8t reliable askes for it.
So if playing in ipv6 enables country's would have an edge over me?
Not to mention i don't have fibre to the property.
It depends how you look at it.
Selfish point of view is if you only consider the broadband user, then there is no actual "need" for it, the only service I am aware of that significantly benefits from ipv6 is the xbox live service, as microsoft use teredo, if you have native ipv6 it makes things much easier as it will use that if available.
However many datacentre's have a big shortage of ipv4, especially in poorer countries, they have a massive headache all because broadband telco's have yet to adopt en masse the technology, so for people in datacentre's its somewhat more urgent. Hetzner as an example have just announced a huge increase in ipv4 allocation prices. It can now cost 100s or 1000s of euros to get an ipv4 range from them. ipv6 remains free.
Without SNI we may have hit critical point years ago.
