Noob quetsion Why there is a dns ( 192 168 * * ) with my google dns that my router is using? And the most important point, Is it safe to use?

If someone attacked my network would my dns ( 192 168 * * ) be a privacy concern?

What?

Okay, little bit of DNS basics:

if you run a commercial router at home, that runs a DNS recursor, which by default just queries your ISP DNS server, which queries another one, and so on. It's DNS recursors all the way down. If you configure your router to use google's DNS, now you're just querying from Google instead your ISP.

You can also run a DNS recursor (and/or an authoritative server) separately (e.g Pihole, Bind9, PowerDNS, etc.) inside your network, and nobody else but you will have access to it. As long as you don't expose the service directly to the wide Internet (so nobody can connect), you're fine. DNS will work for you, but nobody else.

Also, 192.168.x.x IP addresses are private IP addresses, it's only routeable inside your network. Nobody outside can access your stuff with those IP addresses.

I don't know what the question was, but I'm hoping somewhere here you found some information that will help google/bing/duckduckgo around and provide you an answer. There are a lot of sources online for understanding DNS and networking, so you should look into that a bit.
