 ## 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)
+
+1) **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**).
+
+2) **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**
+
+3) **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)**  
+```bash
+# 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
