IPv6 ??

I have Spectrum residential service and several years ago Spectrum started handing out /128 IPv6 addresses, and this would show up automatically (DHCP) in my interface table for my WAN NIC. I have service on a commercial server, unaffiliated with Spectrum, which has given me a /56 IPv6 address assignment for my use and I successfully routed a piece of this group, via my Spectrum connection and a VPN, for use for v6 addresses on our LAN, using OpenVPN. This worked perfectly for a number of years! About a year ago I noted that the VPN routing for v6 addresses stopped working, and apparently Spectrum is no longer gives me a v6 address. NOTHING CHANGED ON OUR END.

Has something changed with Spectrum's policy? I don't need a static v4 or v6 address, just a way of connecting to the IPv6 universe so that I can operate my LAN, so a dynamically assigned (and properly routed) v6 address would work fine.

I read somewhere that Spectrum is now assigning EITHER a v4 OR a v6 address on connection in response to a DHCP client request. Is this the case?

    It's all Greek to me but all i can figure is that you should be getting a /64 if not /60 prefix although i wouldn't be surprised if /60 is only for biz-grade and/or maybe top-tier residential subscribers.

    If it's not happening, you could always try to re-up it on the router with e.g. auto-detect selected in lieu of any more specific connection type.

    Want to say it was /56, and passthrough only back when I tinkered with it years ago.

    Wound up turning it off on my router though because of issues with some games. Since I play nearly 99% on console nowadays, just never bothered with it since.

    I'm not interested in anything bigger than a /128 IPv6 connection from Spectrum since I have a VPN to my server which provides me with a /56, and I can assign v6 addreses to our LAN hosts from this group.. But without even a single IPv6 address (which I used to have) I can't run a v6 VPN from my LAN. I'm interested in Spectrum's policy with regard to assignment of V6 addresses. I don't need a fixed address, just one that works. I repeat, this Used to work, and did so for a number of years, but stopped working relatively recently (last year or so). Nothing has in my hardware or software router configuration which would have caused this.

    I've heard that Spectrum's policy for residential service has changed, and one now gets either a v4 or a v6 address via DHCP (or DHCP6). Can anyone who understands the technology confirm this?

    Tinkered with it at the house for another thread recently. All I did was go into the Asus config and turn it on as Native... left everything at defaults (auto configs).

    Was able to go back in and do both /64 and /56 requests and got both, but did not try any others.

    While the linux box, phones, and streaming devices got along with the v6 fine... the Windoze laptop was still being fussy about it. Since I don't have a need for v6, and all the games I play are still using v4 anyway... just turned it back off again.
