On the last few omnios builds I've having weird issues when the resolver ... turns out if 1 the resolvers is not responding everything is broken?

I would expect it to skip it and try a different one but it never seems to.

Did something change recently ?

I guess I'll add options rotate and see if it's better next time

Doesn't seem to do anything though, resolving like 10 random domains always grab the same nameserver when running it through host <domain>

I just checked it on r151052: inserted a non-existent IP as 1st nameserver in /etc/resolv.conf. The host command returns me a timeout error, but I also got the reply from the 2nd name server. Thus I'm unable to reproduce your problem. No IPv6 in my network, however.

Just one ipv6 and one ipv4 both up, it always seems to go for ipv6 too

I guess I could also try `options timeout:1`

But the other nameserver is back now
