1.- In effect, the system does not provide the number of visitors but the number of IP addresses that have "visited" our site. This means that the number of unique visitors, the number of visitors that visited it once and the number of visitors that visted it more than once is, as a matter of fact, always referring to the IP address that generated them.

For example, the number of unique visitors is identical to the number of unique IP that "visited" our site, while the number of visitors that visited it once is identical to the number of IP addresses that " visited" it once.

2. Every Internet user browsing our site uses an IP address that the systems identifies unequivocally.

3. One IP address is seldom used by only one user. Having in mind that the number of existing IP addresses worldwide is much lower than the number of visitors browsing millions of web sites, each IP address can be used indeeed by an "n" number of visitors.

4. In fact, the same IP address in general, dynamic or static, can be used in the following ways:
4.1. - Entirely or partially by the employees of the same company;
4.2. - By all users of the same wide area network (wan);
4.3.- By different users of the same provider.

Consequently, the number of visitors that really visited our site is impossible to be determined but it is surely much higher than the number of IP addresses used to browse our site and were detected by our system.
