I was surprised today to find that Spectrum doesn't enable IPv6 by default. Only figured this out after way too long trying to ssh into my IPv6-only Hetzner instance. Ended up just paying for an IPv4 address to avoid the hassle. I don't think this is "the year of IPv6" but it might be its decade.

I was dealing with this the other day. Spectrum was giving me IPv6 - annoying when developing an IPv4 service. Ended up switching router to one that only support IPv4 and it reverted back to IPv4. If I plug my MacBook directly into the modem, get ipv6.

  It seems you're running a "service" on a customer line? That's not exactly what they're selling them for... (Though I agree there should be no such distinction, in a real P2P internet)

    Spectrum also sells business internet service, where you can have static IPs, speak to real engineers, etc.

      I'm hoping/assuming/guessing those won't have that odd IPv4/IPv6 switching behaviour...

        >I'm hoping/assuming/guessing those won't have that odd IPv4/IPv6 switching behaviour... As a Spectrum Business customer, I wish I could tell you whether or not that was true, but IPv6 isn't available to me at all. I'd happily (okay, not happily, but I'd be willing to do so) pay for an IPv6 block (I currently pay for five static IPv4 addresses -- one of which is eaten by Spectrum's required router, the other eaten by my own router, but that's a different discussion..Grrr!), but I can't even do that -- as it's not even on offer here (NYC). It seems that there's wide disparity in how/where Spectrum implements its IPv6, so YMMV.

I have used Spectrum and they gave me a v6 route without asking. Maybe your DHCP client or OS was to blame? I am not sure if it shook out via router advertisements or DHCPv6, it just worked with dhcpcd.

Might be a regional thing or something to do with your router. I have Spectrum and my router gets a global IPv4 address and IPv6 prefix over DHCP(4/6) just fine without doing anything special.

I have Spectrum at my house & while they will give me an IPv6 address it doesn't really work. The network offers up a wide range of IPv6 blocks I can choose to use. But whatever IP you use first, that is the only address you ever get traffic for. So the delegation is basically just 1 IP in practice. Also IPv6 doesn't actually work reliably. You'll notice it when browsing the web for example, there are periods of 2-3 seconds without IPv6 connectivity. This does not happen on IPv4.
