There are several actions already under way:
work on a future RFC on "DNS privacy problem statement". Two Internet-Drafts cover this. The work started in the perpass working group and will soon formally move to dnsop.
work on "QNAME minimization", a simple and deployable technique to minimize the amount of data sent to authoritative name servers.
work on encryption of DNS traffic. There are existing solutions (IPsec, DNScrypt) and possible new techniques (an Internet-Draft suggests a new method).
This talk will describe these actions, their current state after IETF 89 in London and the discussions they trigger.
