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
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
Dan, toss me some red balls through window 16022 Ok Angel here they go
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.
