[Dnsmasq-discuss] shortcuts for REFUSED / RCODE

[Ercolino de Spiacico]

Following the man page I can see that we have short syntax to define a 
locally a domain binding using address (or local as we use) directive 
and return accordingly:

local=/example.com/# = 0.0.0.0 (NULL)
local=/example.com/ = NXDOMAIN

In the context of adblocking I am told certain browsers/systems react 
much better when the DNS server returns FORBIDDEN (I guess they mean 
REFUSED which is return code 5 
https://www.iana.org/assignments/dns-parameters/dns-parameters.xhtml#dns-parameters-6) 
as this instructs the query generator (app) to stops hammering again for 
such domain.

It seems like this behavior can be achieved in dnsmasq via the syntax

local=/example.com/127.0.0.1

Great. Since we run this on routers (Tomato) the dsnamsq configuration 
file size matters.


Bottom line: Could we have a shortcut char for REFUSED as well e.g.

local/example.com/%

As an alternative request... is it a good idea to re-thing the shortcut 
approach and simply allow the rfc's RCODE after the latest slash to 
return the correspondent RCODE name? e.g.

local/example.com/2 // ServFail
local/example.com/9 // notAuth
etc?

Thanks
