Commentary:
(maybe a rant, but let's see where it goes ...)
My current ISP, Comcast, provides an excellent IPv6 service.
Dual-stack. An IPv6 address, and the capability to obtain a /60 prefix delegation (though I don't request that level).
The competitors to Comcast in my area are Frontier and GoNetSpeed.
Frontier's IPv6 service is lame (I'm being kind). It is little more than an IPv6 tunnel over IPv4. I tried the service for a while, it seemed to be slow, oh so slow, compared to what I see from Comcast's dual-stack IPv6 service.
When I asked GoNetSpeed about what they provided, I received no response from their customer service. So, a company that apparently wants to gain my custom, but does not take the time to answer emails from a potential customer? OK, I want nothing to do with that company.
And, if I may also add, my current overall view of Comcast is not a good view. On the marketing side, imo, Comcast abuses customers.
However, on the Engineering side of the service they provide, well, their Internet service is tops, from a technical point of view.
And that may be Comcast's problem, i.e., it's marketing folk may be scum, while it's Engineering folk are tops.
imo, nothing more.
