Comment:

 Hi, thanks for this patch!

 > The functions that call them need to check the returned address using
 "tor_addr_port_is_valid()". Most callers will pass 0 for "for_listening",
 because they will be connecting to the address, rather than listening on
 it,

 Please revise the patch to use tor_addr_port_is_valid() not
 tor_addr_is_null().

 These checks are around the wrong way, they should say
 `!tor_addr_port_is_valid()`:
 {{{
 } else if (node->ipv6_preferred || !tor_addr_is_null(&ipv4_addr.addr)) {
 }}}
 {{{
   } else if (!tor_addr_is_null(&ipv4_addr.addr)
 }}}
