How would connections to Google DNS and Level 3 DNS happen?

These showed up in popups for the first time:

"On Sep 15, 2013, Firefox tried to establish a connection to 4.2.2.1 on port 53 (domain). The request was denied via connection alert." but also alerts for 4.2.2.2 through 4.2.2.6

And in quickly after: "On Sep 15, 2013, Firefox tried to establish a connection to 8.8.4.4 on port 53 (domain). The request was denied via connection alert." A similar alert for 8.8.8.8 appeared as well.

I am confused. My Airport Extreme is set to OpenDNS. I use the OpenDNS Updater on my MacBook Pro and Network in System Preferences points the DNS servers tab to the Airport Extreme.

Where do these pop-ups show up?

No matter, some networking applications in your network is (sometimes?) using Google DNS and Level-3 DNS, be it because they are hardcoded to do so, or be it a human configured it or simply raised a DNS query specifying a different resolver address. I also seem to have such an application occasionally querying Google.

The OpenDNS Community has moved!
