Assuming you can install whatever software you like, I recommend running
your own instance of Unbound on your exit node machines. Current Unbound
versions support DNSSEC validation, QNAME minimisation, etc. While using
your ISP's resolvers works as a fallback, a local resolver is better and
easy enough to set up.
