Microsoft announces Zero Trust DNS (ZTDNS). My quick, not-so-well-informed take is that it looks RPZ-like, but seemingly specific to Windows environments with all the bells, whistles, and functions that implies.
#DNS

How does someone trying to find an IP address present a warrant to the dns resolver? Is this a dnssec extension? An AXFR with TSIG/SIG(0)? Or are the warrant & query (and responsive records) transmitted over some other protocol (eg eg dns over postal mail)?

Interesting #DNS issue. I had a domain name with #AWS/Route53 that I registered in 2019 and used until 2021. I shut down the service behind it but kept the DNS configuration intact.

Anybody knows where to get good Internet traffic statistics these days? I'm interested in the protocol mix seen in the backbone, not absolute numbers.

#FRage Vor paar Monaten hatte ich mal das Problem, das ich DNS Einstellungen bei INWX einstellen wollte. Da hat mir jemand einen Tip gegeben, den ich leider nicht notiert hab.
Es geht konkrekt um das einstellen von der IP6 Adresse, ich hab da ne Domain auf ne IP6 weitergeleitet, aber ich kriege kein ping wenn ich diesen auf die IP6 mache.

This was a fun article to produce. Uncovering Internet activity most overlook, explaining the process, and maybe provoking research ideas. We could do this 24x7.

If anyone from #Kroger happens to see this, your iPhone app has some #DNS borkage. When the app is launched, it queries an A record for "https://​app-measurement[​.]com/sdk-exp" (munged to prevent autolinking here). It's trying to resolve a URI instead of a hostname label.
