The DNS Camel

-
This led me to propose a last-minute talk to the DNSOP Working Group, which I tentatively called ‘ The DNS Camel, or, how many features can we add to this protocol before it breaks ’. This ended up on the agenda as ‘The DNS Camel’ (with no further explanation), which intrigued everyone greatly. I want to thank DNSOP chairs Suzanne and Tim for accommodating my talk, which was submitted at the last moment!

Just this week, the U.S. Cybersecurity and Infrastructure Security Agency shared ( as reported in the Wall Street Journal) that approximately 30% of both private-sector and government victims linked to the hack had no direct connection to SolarWinds.
