[Dnsmasq-discuss] sorting out the right ipv6 addr to choose and name in a source specific world

I have been wrestling with prefix coloring, where choosing a "best" prefix would be of use in (for example) reducing the problems induced by happy eyeballs when more than one ipv6 prefix is present and several other scenarios. There are many parts to this - one is in addressing, the other in DNS,

I strongly suspect an ipv6 fragmentation handling bug in the kernel version cerowrt uses. Have tons of evidence pointing to that now, starting with some tests run last year from iwl and also the tests that netalyzer was doing. And: I just locked up the box completely while doing some dnssec stuff.
