Alas, the second interface never worked. More flailing about revealed that I'm being given a /64 prefix delegation. /64 is by convention the smallest subnet you can have in IPv6, or so I've been told. So I'll need maybe a /60 delegation from Cox to have more than one LAN segment.
Publicly and by convention yes, but you can split it up locally. Dishing out smaller subnets publicly would make the internet routing tables explode very quickly. Even with /64 it's bad enough.
The saga ended with a phone call to a Cox level 2 technician who said, basically, that's too bad. He suggested that their business class service might be able to offer more. Their home service apparently assumes you'll have a single computer connected to the cable modem, and who would ever need more than one subnet!
That has been a fairly safe assumption for the last ten years or more - last time I had a consumer class modem/router, it certainly only had a LAN and a WAN side. Maybe just ignore your IoT LAN for now - most of those device won't speak IPv6 anyway (I suspect). Or ignore your wired LAN side.
If any of you v6 experts have suggestions I'd be glad to revisit. I'd even consider purchasing a different router. Another possibility might be suggestions on how to break a /64 delegation into multiple subnets.
_If_ your router is up to it, it's not a big deal.
Yes Per, it was fun. But also frustrating. Unless my environment is somehow unique I think that full deployment of v6 will be difficult indeed.
Swisscom is deploying IPv6 to all new customers. I think perhaps having two 2 LAN segments is a little unique. -- Per Jessen, Zürich (10.6°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
