How to handle subdomain not to be resolved externally?

[ComputerKid]

Hi,
I'm using internally a subdomain of my tld, let's call it sub.tld.com.
I'm fighting the issue that for example when I ping pc1.sub.tld.com i get the local IP 192.168.1, but if i ping pc99.sub.tld.com (which does not exist) I get the ip of my tld. What I have to do that unbound will answer that this host is not reachable?

Regards.
Martin

By "using internally", do you mean that you have set System -> Settings -> General -> Domain to "sub.tld.com"?

Does public DNS for "tld.com" have a wildcard?

You could try chaning Services -> Unbound DNS -> General -> Local Zone Type to "static" instead of "transparent"

Ok, seems that my hosting partner has a wildcard entry...i removed it and hopefully this help, have to wait up to 48 hours. On the other side would it be nice if there is a possibility to exclude specific domains to be resolved externally...if someone has an idea?

Sorry I have overseen this post I'll try with static zone.
