Internet connection between two PC, both under different ISPs
Hi all.. I have a doubt.. Please go through this scenario :
PC :Personal Computer
ISP : Internet Service Provider, which gives the IP Address to the PC under him.
Suppose I have PC-A running under ISP-A and another PC-B running under ISP-B. Both PCs A, B are running in different cities.
Now Im running an application on PC-B which listens for the messages that should be processed and PC-A want to send to messages to the application listening on PC-B.
For this situation how does PC-A does connect to PC-B i.e. what is the IP Address of the PC-A to get connected.
Do I need to give IP of the ISP-B.
Please anyone tell me how to connect.
Thanks in advance
