An increasing number of your competitors provide native IPv6 transit on their residential boradband plans. Whilst tunnel mechanisms exist to use IPv6 over IPv4, this requires a relationship with a second ISP and the customer's own specialised equipment.
I'd like TalkTalk to natively provide an IPv6 service on residential lines, ideally with a static block allocation. It is becoming a feature that customers not only expect from their service, but also need to access the vast portion of the IPv6 Internet.
A number of TalkTalk's existing customers have asked for this in the forums over the last 7 years, but I hadn't seen an "Idea" raised to track it yet.
