Why is IP whois lookup important?
With an IP address, the sender of an IP address can be tracked. For instance when a person is visiting a website, the IP address of the visitor is sent to the web server via the web browser. If the webmaster wishes to determine where the visitor is from, he can perform an IP whois lookup to identify the network provider and in some cases the location (region) of the online visitor.
IP addresses are sometimes also logged in statistical software, so it becomes easier to segment visitors at a general level based on demographic and topographic origins, which can be valuable for the business marketing strategy.
