--------------------------------+--------------------------------
 If they don't have usable Address, ORPort, or interface addresses, relays
 (and bridges) should get their local hostname, look
 up its addresses, and use them as its IPv4 and IPv6 addresses.

 We propose to use the same underlying lookup functions to look up the IPv4
 and IPv6 addresses for:
   * the Address torrc option (see section 3.2.1), and
   * the local hostname.
 However, OS APIs typically only return a single hostname.

 The hostname lookup should ignore private addresses on public relays. If
 multiple IPv4 or IPv6 addresses are returned, the first public address
 from
 each family should be used.
