Yeah, yeah, but what are YOU doing to identify my signips correctly?
At the first visitor’s appearance on the site by your unique URL (which also already contains partner’s login that brought the person to the site), we insert him cookie with your code. Naturally, it is not too reliable, that’s why we register IP address of the subnetwork from which the click was made into our database, and further if during the registration the partner identifier was not determined through URL or cookies, we try to determine the identifier with a mask of the subnetwork. It helps even when the person has called back the provider to change the IP address on purpose.
