Abstract
Managing encrypted network traffic using Domain Name System responses includes requesting an address associated with a domain name from a resolution server, the domain name included in a predetermined set of domain names for which secure requests are to be identified; receiving a response from the resolution server including one or more addresses associated with the domain name; associating with the domain name a particular address selected from the received addresses; receiving a request to resolve the domain name; sending a response to the domain name resolution request, the response including the particular address associated with the domain name; receiving a secure request for a resource, the secure request directed to the particular address associated with the domain name; and determining that the secure request is directed to the domain name based on the association between the particular address and the domain name.
