( 8 8 8 8 ) ( 8 8 4 4 ) ( 192 168 1 1) my home router uses these three
dns. shouldnt there only be the first and second dns ( google dns ) ?
+  is it secure to use the 3rd dns if my network got comprmised?

Im assuming your third DNS is your gateway? In which case, that’s very
normal to have

Describe ‘safe’ nothing is entirely ‘safe’. What I can say is that it
is normal to have this, it allows your router to query local cached
DNS to save it asking external servers making the requests faster

You're fine. The third DNS is the gateways (probably). There's nothing
weird or dangerous about having 3 DNS servers or having your gateways
as one of them.

The only time I would be concerned is if your DNS got changed to some
IP that wasn't a well-known DNS server (or the gateway).

Why would it not be safe?
