commit eae68fa2d2bde931bf8b9115f7a9cb7a0f0c9073 Author: Philipp Winter phw@nymity.ch Date: Wed Jul 27 12:01:03 2016 -0400

Initialise DNS TTL for A and AAAA records.

So far, the TTLs for both A and AAAA records were not initialised, resulting in exit relays sending back the value 60 to Tor clients. This also impacts exit relays' DNS cache -- the expiry time for all domains is set to 60.
