Primary and secondary — why there are two

208.67.222.222 is OpenDNS's primary address — the one your device queries first. OpenDNS also publishes a secondary, 208.67.220.220, as an automatic fallback. Configuring both is recommended: DNS is critical infrastructure, and a second address means a momentary problem with one server doesn't take your connection offline. Both resolve the same names with the same features, so there's no downside to listing both.

Time 208.67.222.222 from your connection

This runs a live timing check against OpenDNS's encrypted DoH endpoint — a browser can't query the raw IP 208.67.222.222 directly, so this is the closest honest measurement of that resolver from your network. Nothing is fabricated: if the endpoint can't be reached or read, the tool says so instead of guessing a number.

Runs in your browser against the resolver's DoH endpoint; nothing is stored. For a full multi-resolver comparison on your connection, use the DNS speed test.

Should you use it?

A long-established resolver with phishing protection and optional content filtering, backed by Cisco's network.

Best for: Content filtering, Phishing protection, Reliability.

Like any public resolver, OpenDNS adds a small round trip compared with your ISP's default DNS, and it can't optimize CDN routing as tightly as a resolver peered locally with your network in every case. Use the live timing check above, or the full DNS speed test, to see whether it's actually faster than what you have now.

To use OpenDNS, set 208.67.222.222 as your primary DNS and 208.67.220.220 as the secondary — see the device and router setup guides or read the OpenDNS full review .

Is 208.67.222.222 faster than my ISP's DNS?

Often, but it depends on your location and network. Use the timing button above to measure it from your own connection, or run the full DNS speed test.

Do I also need the secondary 208.67.220.220?

It's recommended. 208.67.222.222 is OpenDNS's primary address and 208.67.220.220 is the secondary. Configuring both means that if the primary is briefly unreachable your device falls back to the secondary automatically instead of losing DNS. They resolve identically — the second address is purely a backup.
