Pi-Hole in Homenetwork

I followed this tutorial: World's Greatest Pi-hole Tutorial - Easy Raspberry Pi Project! - YouTube

Installed in goodolddell
192.168.1.51
Pi-hole goodolddell

DNS Settings on Router

Make Pi-hole the Network’s DHCP (so all clients use it as DNS)

Goal: Your router can’t set custom DNS, so we’ll let Pi-hole (192.168.1.51) hand out IP addresses and advertise itself as DNS. This gives you network-wide ad-blocking without touching per-device settings.

Prereqs (do these first)

Give Pi-hole a fixed IP
- Make a DHCP reservation on your router for the Dell/Pi-hole at 192.168.1.51 (MAC = Dell’s NIC).
- Or set a static IP on the Pi-hole host (keep it in the router’s LAN subnet; gateway = 192.168.1.1).
Know your LAN details
- Router (gateway): 192.168.1.1
- Pi-hole server: 192.168.1.51
- Choose a DHCP range that avoids statics, e.g. 192.168.1.100–192.168.1.200
Make sure Pi-hole web UI works
- Open http://192.168.1.51/admin
- If needed: sudo pihole -a -p to set/change the password.

Step 1 — Configure Pi-hole DNS (upstream)

In Pi-hole → Settings → DNS:

Choose upstream resolvers (e.g., Cloudflare 1.1.1.1 / 1.0.0.1 or Quad9).
(Optional) Conditional Forwarding to see client hostnames:
- Local network/CIDR: 192.168.1.0/24
- IP of router: 192.168.1.1
- Local domain name: e.g. home (or leave blank if unsure for now).

Click Save.

Step 2 — Enable Pi-hole’s DHCP (but don’t disable router yet)

UI method
Pi-hole → Settings → DHCP:

✅ Enable DHCP server
Range: 192.168.1.100 to 192.168.1.200
Router (gateway): 192.168.1.1
(Optional) Domain name: home
Save

CLI equivalent (optional)

# On the Pi-hole host:
sudo pihole -a enabledhcp 192.168.1.100 192.168.1.200 192.168.1.1

Todos

disable blocking - automation: should be easy for every user
