   **Default:** `false`.
 * `keepAliveInitialDelay` {number} If set to a positive number, it sets the initial delay before
   the first keepalive probe is sent on an idle socket.**Default:** `0`.
+* `autoSelectFamily` {boolean}: If set to `true`, it enables a family autodetection algorithm
+  that loosely implements section 5 of [RFC 8305][].
+  The `all` option passed to lookup is set to `true` and the sockets attempts to connect to all
+  obtained IPv6 and IPv4 addresses, in sequence, until a connection is established.
+  The first returned AAAA address is tried first, then the first returned A address and so on.
+  Each connection attempt is given the amount of time specified by the `autoSelectFamilyAttemptTimeout`
+  option before timing out and trying the next address.
+  Ignored if the `family` option is not `0` or if `localAddress` is set.
+  Connection errors are not emitted if at least one connection succeeds.
+  **Default:** `false`.
+* `autoSelectFamilyAttemptTimeout` {number}: The amount of time in milliseconds to wait
+  for a connection attempt to finish before trying the next address when using the `autoSelectFamily` option.
+  If set to a positive integer less than `10`, then the value `10` will be used instead.
