Hi,

I've tried to find this out through reading and googling and I can't find
any obvious solution so I was hoping someone might know a trick that would
help me. I'm trying to do some sort of domain to domain translation so
that when a query for the a record of host1.firstdomain.tld is received,
dnsmasq does a lookup for host1.seconddomain.tld and returns the IP as if
the client had asked for host1.seconddomain.tld.

For an individual host this is much the same as a CNAME record but I need
to be able to specify the hostname dynamically so that
%anything%.firstdomain.tld is a CNAME for %anything%.seconddomain.tld.
Wildcards don't help either as this is not a case of
%anything%.firstdomain.tld being a CNAME for
specifichost.seconddomain.tld.

>From what I gather, this is what a DNAME record will do although support
for this type of record seems a little scarce and dnsmasq doesn't support
these directly. The purpose is not nefarious and it is all being done for
internal to internal translation. I've not gone into why I need this in
any great detail but it's nothing dodgy.

The --synth-domain feature suggests that there is some sort of engine to
create dynamic replies based on the query but I need the equivalent of:
--synth-domain=firstdomain.tld,seconddomain.tld

Can anyone help?

TIA,

Adrian
