What is 208.67.220.220?

208.67.220.220 is the secondary DNS resolver address for OpenDNS, operated by Cisco — the backup your device falls back to when the primary (208.67.222.222) isn't answering. It resolves the same names, from the same service, as the primary. A long-established resolver with phishing protection and optional content filtering, backed by Cisco's network.

How 208.67.220.220 works as a secondary address

208.67.220.220 is a backup resolver. Your operating system sends each DNS query to your primary DNS server first — for OpenDNS that's 208.67.222.222 and only turns to 208.67.220.220 if the primary doesn't answer in time. It isn't queried in parallel, and it isn't "faster" or "slower" than the primary — it points to the same OpenDNS service. The reason to set it is resilience: if the primary has a brief hiccup, your device keeps resolving names instead of failing.

Set 208.67.222.222 as your primary DNS and 208.67.220.220 as the secondary to get OpenDNS either way.

Time 208.67.220.220 from your connection

This runs a live timing check against OpenDNS's encrypted DoH endpoint — a browser can't query the raw IP 208.67.220.220 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 .

What's the difference between 208.67.220.220 and 208.67.222.222?

208.67.222.222 is OpenDNS's primary DNS address and 208.67.220.220 is the secondary. Your device queries the primary first and only falls back to 208.67.220.220 if the primary stops answering. Both point to the same OpenDNS service with the same features, so the secondary is there for redundancy, not extra speed — set 208.67.222.222 as your first DNS entry and 208.67.220.220 as the second.
