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?
Sounds like you may want something like PiHole. You can set your local dns using either the web interface or by editing the config at: “/etc/pihole/custom.list”
