Block Google DNS on Netgear Routers
Step 1: Start by adding the playmoTV DNS to your router via our router setup guide, but don't leave the router setup page.
Step 2: Click on Advanced tab and copy (or remember) the IP address of the router. Then focus on the left sidebar, click Advanced Setup and Static Routes.
Step 3: Now, for the real deal:
Step 3.1: Tap the +Add button. Enter a Route name (you have to do three routes so name them something like "blockgoogle1", "blockgoogle2" and so forth.
Step 3.2: For the Destination IP enter 18.104.22.168
Step 3.3. For the Subnet Mask enter 255.255.255.255
Step 3.4. For the Gateway enter the IP address from step 2.
Step 3.5. In the metric field enter 2.
Step 3.6. Press Apply / Save Settings.
Step 4: Save Settings, and ensure that everything has been entered by clicking Show Routing Table.
Step 5. After you have done this find your router's IP address (probably 192.168.1.1) in the main settings page and write it down or remember it.
