[DNS] A and AAAA for sub sub domains: fast /easy question (hopefully): give me a confirm/advice, please

[wireless]

Hi everybody,
I need a fast and easy confirm.
Actually I have done

uci add_list dhcp.@dnsmasq[0].address="/home.lan/10.10.10.1"
uci commit dhcp
/etc/init.d/dnsmasq restart

to "redirect" all requests for domain *.home.lan to 10.10.10.1
Now, if I want to redirect the requests of a single subdomain of home.lan, for example nas.home.lan and its related sub sub domains *.nas.home.lan, f.e.:

ftp.nas.home.lan
webdav.nas.home.lan

to another ip, f.e. 10.10.10.2, I can just do:

uci add_list dhcp.@dnsmasq[0].address="/nas.home.lan/10.10.10.2"
uci commit dhcp
/etc/init.d/dnsmasq restart

?

In other words, dns understands that there is a different ip for the more specific subdomain nas.home.lan, even if it has already an entry for home.lan?

Thanks!!!

ps: the [0] in the dhcp.@dnsmasq[0] to what refer? Should/Might use dhcp.@dnsmasq[1]?

Yes.

The UCI system

No. You have only one dnsmasq instance running.

You probably want to use selective DNS forwarding.

Thanks to both! But now I have a curiosity....
Is it supported also some sort of pattern matching or wildcard? If I just want to route *-test.myDomain.com, I can just use this string in the hostname(s) part? Or this is the forwarding use case?

[pavelgl]

Wildcards are not supported and the domain name in the address or server options cannot start with a hyphen. In my opinion, what you want to achieve (*-test.myDomain.com) is not possible.
