Comment (by MrSquanchee):

 > Should we make a function similar to tor_addr_is_valid_ipv4h
 I provided functions (network and host order) for both ipv4 and ipv6.
 {{{
 int
 tor_addr_is_valid_ipvn(const tor_addr_t *addr, int for_listening) {
   return tor_addr_is_valid(addr, for_listening);
 }

 int
 tor_addr_is_valid_ipvh(const tor_addr_t *addr, int for_listening) {
   tor_assert(addr);

   if (for_listening) {
     return 1;
   }

   if (addr->family == AF_INET) {
     return htonl(addr->addr->in_addr) != 0;
   } else if (addr->family == AF_INET6) {
     uint32_t *ipv6 = tor_addr_to_in6_addr32(addr);
     return !(htonl(ipv6[0]) == 0 &&
              htonl(ipv6[1]) == 0 &&
              htonl(ipv6[2]) == 0 &&
              htonl(ipv6[3]) == 0);
   } else {
     return 1;
   }
 }
 }}}

 The other only ipv4 functions are tor_addr_port_is_valid_ipv4[h/n].
 I think we should leave them as it is.
 What do you say ??
