Router — protect every device at once

Change DNS on your router once, and every device on the network is protected — phones, TVs, consoles, IoT, guest devices. Menu wording differs by vendor; the DNS setting is usually under WAN, Internet, or DHCP.

  1. Log into the router admin page (typically 192.168.1.1 or 192.168.0.1).
  2. Find DNS settings — usually under Internet, WAN, or DHCP Server.
  3. Change DNS mode to Manual (or similar).
  4. Set Primary DNS to 210.187.49.141. Clear any secondary DNS or set it to the same IP.
  5. Save and reboot the router.
  6. Reconnect a device to Wi-Fi (or wait for DHCP lease to refresh).
If Android devices ignore router DNS, set Private DNS manually on each — see the Android page. Same for iOS with the Configuration Profile.

Troubleshooting
Router rejects the setting / reverts to ISP DNS.
Some ISP-supplied routers lock DNS. Put the router in bridge mode and use your own, or set DNS per-device.
Only the WAN DNS field exists, no LAN / DHCP DNS.
Setting WAN DNS is enough on most consumer routers — the DHCP server automatically passes the same DNS to clients.
Android 9+ phones still using ISP DNS.
Private DNS on Android 9+ overrides DHCP. Set Private DNS to the ScamLens hostname on each device.
