Something fun to peruse over the weekend...we've started a daily dose of the top 500 #DNS domains seen on the Quad9 recursive resolver on #GitHub.

We're excited, are you? github.com/Quad9DNS/qua...

"Making the internet predictably safer" titles this image of an infinity loop design which surrounds the BforeAI logo on the left and the Quad9 logo on the right. The loop is divided into 5 sections with different colors to describe the collaboration between the two organizations, as follows: 1) PreCrime Intelligence predicts; 2) PreCrime Intelligence disrupts and shares; 3) Quad9 blocks; 4) Automatically protects; and 5) Quad9 provides telemetry data.

A quick look at our Newly Observed Domain data over the last 30 days says that there have been more than 6,000 domains containing the string 'dns' which have seen for the first time- it appears that the #DNS is a fairly popular topic to reference in domain names. Who knew?
