> Many large cable ISPs in the USA have been running IPv6 internally for years now.

CableOne/Sparklight says hi, because they have zero intention on deploying v6 for the foreseeable future.

Not sure I would classify CableOne/Sparklight as a large cable ISP. Their website says they service about 900k customers. Even if all of these customers had internet service this would put them fairly far down the list of ISPs. I would more classify them as a medium sized ISP.
