+Use `require('dns')` to access this module. All methods in the dns module use
+C-Ares except for `dns.lookup` which uses `getaddrinfo(3)` in a thread pool.
+C-Ares is much faster than `getaddrinfo(3)` but, due to the way it is
+configured by node, it doesn't use the same set of system configuration files.
+For instance, _C- Ares will not use the configuration from `/etc/hosts`_. As a
+result, __only `dns.lookup` should be expected to behave like other programs
+running on the same system regarding name resolution.__ When a user does
 `net.connect(80, 'google.com')` or `http.get({ host: 'google.com' })` the
 `dns.lookup` method is used. Users who need to do a large number of lookups
 quickly should use the methods that go through C-Ares.
