Acting as a DNS-level ad blocker, Pi-hole intercepts and blocks requests to known ad and tracking domains before they ever reach your devices. It’s fast, private, and works network wide.

Because Pi-Hole is intercepting DNS requests, we need to be careful about its availability, if your DNS goes down, your internet goes down. That’s why, in my VLAN segmented home network, I decided to go with Redundant/highly available Pi-hole deployment for resiliency.
