Comment(by marek):

 I cross-checked `tor_addr_is_internal_`[1] against nmap [2] [3]. Addresses
 nmap treats as private/unroutable but tor doesn't (comments mostly from
 nmap):

 {{{
     6/8         /* USA Army ISC                 */
     7/8         /* used for BGP protocol        */
     55/8       /* misc. U.S.A. Armed forces    */

     224-239/8      /* is all multicast stuff */
     240-255/8      /* is IANA reserved */

     192.0.0/24      /* looks like RFC5736 */
     192.0.2.0/24        /* is reserved for documentation and examples
 (RFC5737) */
     198.18.0.0/15      /* is used for benchmark tests by RFC2544 */
     198.51.100.0/24  /* is reserved for documentation (RFC5737) */
     203.0.113.0/24    /* is reserved for documentation (RFC5737) */

     192.88.99.0/24    /* is used as 6to4 Relay anycast prefix by RFC3068
 */
 }}}
