[Dnsmasq-discuss] dnsmasq's behaviour with configured static hosts is unintuitive

[Aaron Jones]

Hello.

I'm trying to force queries for specific names to not be forwarded along
to recursors, and be answered locally. The normal way to do this is to
put such address/name pairs in hosts(5), or you can add a --host-record=
option to the configuration file.

That works okay.

However, I'm trying to force a specific address family. Specifically,
these records are for host names on a VPN, and the VPN is IPv6 only. So,
for example, given the following configuration option:

--host-record=foo.example.org,fd00::1

Or given the following hosts(5) entry:

fd00::1 foo.example.org

... will result in an AAAA query for the name returning fd00::1, but an
A query is forwarded along to the configured recursors, instead of
dnsmasq replying with NODATA.

This seems wrong.

I tried to explicitly indicate that there is no IPv4 address, but this
option has no effect:

--host-record=foo.example.org,,fd00::1

... and this option returns the address exactly as given:

--host-record=foo.example.org,0.0.0.0,fd00::1

Any pointers?

Regards,
Aaron Jones
