How to set up OpenDNS or Google DNS on Windows 10

Point Windows 10 at free public DNS to bypass ISP resolver issues that make sites look down only for you.

Why change DNS on Windows 10?

ISP DNS delays after IP changes, or overloaded resolvers, cause timeouts while the website itself is online for the rest of the world.

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

Configure DNS on Windows 10

  1. Open Settings → Network & Internet → Status → Change adapter options (or Control Panel → Network and Sharing Center → Change adapter settings).
  2. Right-click your active Wi‑Fi or Ethernet adapter → Properties.
  3. Select Internet Protocol Version 4 (TCP/IPv4) → Properties.
  4. Select Use the following DNS server addresses.
  5. Enter OpenDNS 208.67.222.222 and 208.67.220.220, or Google 8.8.8.8 and 8.8.4.4.
  6. Click OK, then Close. Optionally repeat for Internet Protocol Version 6 (TCP/IPv6) with IPv6 DNS addresses.

Flush DNS on Windows 10

Clear cached lookups after you switch resolvers.

ipconfig /flushdns
  1. Open Command Prompt as administrator.
  2. Run ipconfig /flushdns and press Enter.
  3. Optionally run ipconfig /registerdns, then restart the browser.

Verify it worked

Visit the site again. If mobile data works and home Wi‑Fi still fails, set the same DNS on your router so every device benefits.
