Hi, I am a total newcomer when it comes to DNS.
I know what it is and what it does, and the fundamentals (What is A,AAAA,TXT,MX-Record, etc.)
Now I want to try to setup my own dns on my local network.
What do I want to achieve?
I have a public TLD (example.com). I have a service like "myservice.example.com" which resolves to my routers public IP.
I want clients from my local network to get a different/local IP address (like 192.168.2.5) for myservice.example.com instead of my routers WAN Address, so I can access the local service without sending traffic out over the WAN. (And it also works in case of internet outage)
For every (locally) unknown domain (like google.com), I want that DNS server to upstream to a global one like 8.8.8.8
Any Ideas on where to start?
