9 years ago Hi @adamfisk - since it's possible to specify a custom host resolver when bootstrapping, it should be possible for the user to implement any custom DNS resolution system, including always using Google DNS (if desired). Do you think that addresses your concern from this issue?
(We actually do make use of LP's pluggable name resolvers in BrowserMob Proxy, allowing users to use the dnsjava DNS library instead of the default JDK name resolution.)

We might want to always use Google DNS?
