Wildcard subdomains with dnsmasq
Solution 1:
In the dnsmasq.conf file, add the line
address=/.domain.tld/192.168.0.1
But use the IP you actually want as that end bit
Solution 2:
While the accepted answer may have solved the author's problem, it is misleading as it suggests that the leading dot would match subdomains only, which is not true.
dnsmasq ignores any leading dots, so that
address=/domain.tld/192.168.0.1
is equivalent to
address=/.domain.tld/192.168.0.1
or even
address=/......domain.tld/192.168.0.1
As of now (dnsmasq v2.76), there is unfortunately no way to specify some things (server, address, ipset) for
- a single domain name only, i.e. domain name without its subdomains
- only for the subdomains of a domain name
The only thing you can do, is to specify something for a domain name and all its subdomain and have override it for specific subdomains, e.g.
address=/domain.tld/192.168.0.1
address=/sub.domain.tld/10.10.0.1
This single domain name only case, may be tackled with different options, such as host-record, srv-record, which may be sufficient in some cases, but certainly not in all. It won't work for example, if you really need to use the server or ipset option for a single domain name only.
