While we’re listening in Washington to the final “What’s Next in DNSSEC” session at the FOSE conference, Wolfgang Nagele reported on Twitter today that the D, K and E DNS root servers (operated by the University of Maryland, RIPE NCC and NASA, respectively) are serving the DNSSEC-enabled root zone.  As this story in The H Online notes, “this means that seven of the 13 central root servers which constitute the Domain Name System (DNS) responsible for domain name resolution on the internet will then return signed responses.”  (Because these are prototype signed zones, they cannot be validated until the full root is signed, which is expected to occur July 1.)
