How to set up OpenDNS or Google DNS on ChromeOS

Chromebooks expose DNS under the network’s network details panel.

Why change DNS on ChromeOS?

School and café networks sometimes break resolution; custom DNS restores access to otherwise healthy sites.

Recommended public DNS servers

  • OpenDNS (Cisco): 208.67.222.222 / 208.67.220.220
  • Google Public DNS: 8.8.8.8 / 8.8.4.4
  • Cloudflare DNS: 1.1.1.1 / 1.0.0.1

Steps for ChromeOS

  1. Click the clock area → the gear (Settings) → Network.
  2. Select the connected Wi‑Fi (or Ethernet) network.
  3. Open Network or Network details.
  4. Find Name servers / Automatic name servers and switch to Google name servers, or Custom name servers.
  5. For custom, enter 8.8.8.8 and 8.8.4.4 or OpenDNS 208.67.222.222 and 208.67.220.220.
  6. Close the panel; ChromeOS applies the change for that network.

Refresh DNS on ChromeOS

Reconnect to clear cached lookups.

  1. Disconnect from the Wi‑Fi network and reconnect.
  2. Or toggle Wi‑Fi in the quick settings panel.
  3. Hard-refresh the tab with Shift+Reload.

Verify it worked

Open a new tab to the site. If a managed school account locks DNS, ask the administrator or use a personal network.
