That doesn't mean it can't be ULA. And it would be hideous but you can use LL if you flatten the broadcast domain. There are lots of reasons why this isn't the best idea but you don't know everyone's network, so saying "that's bad and I'd never do it so we shouldn't support it" at the network layer isn't a reasonable answer. marka> The CPE is a SITE boundary.

And the same could be said of RFC 1918 but ISPs have used that for thousands of homes, crossing thousands of CPEs. Not the best choice and not your choice but it does work for some folks. "site boundary" and what is "local" in ULA have never been well defined because of this. _______________________________________________ dns-operations mailing list dns-operations@lists.dns-oarc.net https://lists.dns-oarc.net/mailman/listinfo/dns-operations
