 Note that various networking APIs will call `dns.lookup()` internally to resolve
-host names. If that is an issue, consider resolving the hostname to and address
+host names. If that is an issue, consider resolving the hostname to an address

 networking APIs (such as [`socket.connect()`][] and [`dgram.createSocket()`][])
 allow the default resolver, `dns.lookup()`, to be replaced.
