Assuming it can't actually look at routing tables, I'd start with ping/ICMP.

After that, assuming it has to be TCP, I'd prefer something above 1024,
which is the "user" address space. That should get you the information
you need unless it specifically requires an ACK and not just communication
back.

If it can get the proper information from UDP, port 53 is koshier with
me. My problem with port 53 TCP is that it is used for DNS zone
transfers, as well as a security exploit not too long ago. This is why
people filter it out.

Btw, my first exposure to doubleclick and Global Dispatch was during 
active attempts by others to exploit DNS servers.

Ciao,
