And it doesn't seem to be a show stopper for a lot of very large carriers.Primarily the ability to end-to-end authenticate end devices. The primary and largest glaring issue is that DHCPv6 from the client does not include the MAC address, it includes the (I believe) UUID.We have to sniff the packets to figure out the MAC so that we can authenticate the client and/or assign an IP address to the client properly.It depends how you're managing the network. If you're running PPPoE you can encapsulate in that. But PPPoE is very 1990 and has its own set of problems. For those running encapsulated traffic, authentication to the modem MAC via DHCP that becomes broken. And thus far, I have not seen a solution offered to it.
I was honestly more interested in the bloat angle, but this sounds like a backend problem of your own making most likely. But I'm not motivated to see if it's actually the case or just a misunderstanding.
Secondly - and less importantly to deployment, IPv6 also provides a layer of problematic tracking for advertisers. Where as before many devices were behind a PAT, now every device has a unique ID -- probably for the life of the device. Marketers can now pinpoint down not just to an IP address that identifies a single NAT interface, but each individual device. This is problematic from a data collection standpoint.
I guess you've not heard of privacy addresses. Or DHCPv6. Mike
