Sure, you can buy a static IP and forward ports, but that comes with cost, security risks, and the chance of exposing your whole network. I wanted none of that. I didn’t want to:
So I started looking for a simpler, safer way.
I have an old Raspberry PI 3 that I used during my college days for applications like drones and robotics. Recently, I decided to repurpose it to run a simple Pi-hole setup to block ads across my home network and devices. One day, my RPi unexpectedly froze, and I had no idea that my DNS requests were failing until I noticed connectivity issues. A reboot resolved the problem, but it made me realize the need for proactive monitoring. Since my router is configured to use Pi-hole as both the primary and secondary DNS (yes, I know I should have a better failover strategy but for now, it works fine), a failure like this can disrupt my entire network.
