- You can find the IP addresses that have been registered by sending
- ICMP_ECHO request (ping) packets to the broadcast address for your
- net. I didn't know about MacTCP not registering it's IP address
- until it was used. This explains why I wasn't getting everyone's
- IP address back when I pinged broadcast, though they were all up
- and connected to the net.
