[Dnsmasq-discuss] options for --all-servers?

[Petr Menšík]

Hi Matt,

can you describe better, what are you trying to archieve?

DNS protocol is query-response protocol. It should always receive some
reply. I don't think any resolv.conf options are parsed by dnsmasq. It
reads only nameserver or search directives I think.

It is possible to limit some domains and sent them to specific servers.
Can I ask why some servers should be worked around? I think
--server=/special.domain/1.2.3.4 should be used instead to handle
domains, which normal upstream resolvers should not be used.

I think it expects all those servers work the same way. If they don't,
you should try to make them that way. Try making dnsmasq treat only some
of them special way to set of domain(s) only.

Cheers,
Petr

The docs and man and forum archives seem to indicate it’s completely global, but I figured I’d ask the experts.
