3. Q. What are private IP addresses? A. The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets (local networks): 10.0.0.0 - 10.255.255.255 172.16.0.0 - 172.31.255.255 192.168.0.0 – 192.168.255.255 Most of the rest of the IP addresses are public A port number really an extension of an IP generally written as 192.168.100.101:16005 http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers

4. A port number represents an endpoint or "channel" for network communications. Port numbers allow different applications on the same computer to utilize network resources without interfering with each other. A socket represents a single connection between two network applications. These two applications nominally run on different computers. http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers

8. Ports and IP's are commonly blocked by firewalls and institutional policies. You must have at least some ports open in order to have seismology programs work To establish a connections between two computers you need to know the IP of the machine and it must appear to be a public IP. You also must know the port number that the module is opening the socket on.
