The Location DNS Configuration button will bring you to the configuration page, which shows Anycast DNS and upstream DNS addresses, plus one-click copy and OS-specific setup steps (Windows example shown:
 

Anycast DNS addresses:

166.117.57.142
166.117.57.146

Upstream DNS (fallback) addresses:

166.117.243.181
166.117.243.23

Windows quick setup (adapter level):

1. Open Settings → Network & Internet → Advanced network settings → More network adapter options.
2. Right‑click active adapter → Properties → select Internet Protocol Version 4 (TCP/IPv4) → Properties.
3. Use the following DNS server addresses → enter CyberFOX Anycast IPs above.
4. (Optional) Enter Upstream IPs as Windows fallback.
5. Click OK, then test via Visibility Report and Test Page.

Best practice: Avoid mixing non‑CyberFOX resolvers in DHCP/router lists. Many devices use round‑robin; mixing resolvers can cause intermittent bypass.
