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.
It's bad with IPv4 not being set up in a hierarchical manner and worsened with address blocks moving around as they're sold. IPv6 was set up so that routing is hierarchical, which reduces the routing table size.
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.
Many now have a guest LAN. The modem I have, in gateway mode, supports this.
Swisscom is deploying IPv6 to all new customers. I think perhaps having two 2 LAN segments is a little unique.
You have more than one segment in many businesses, especially when VLANs are used. I recently did some work at a business where admin and production were on separate switches (the owner had some funny ideas about networks). All the LAN jacks were colour coded as to which network they were on. I don't think they had IPv6 though. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
