Usage of the IP address of the visitor by Google Analytics Cookies

Each computer and device connected to the Internet is assigned a unique number as an Internet protocol (IP) address. Since these numbers are usually assigned to countries in blocks, an IP address can often be used to identify the country, the province and the city from which a computer connects to the Internet. Google Analytics collects the IP address of the website visitors to provide an indication of their geographic location. This method is known as IP geolocation. Google Analytics does not report information related to the actual IP addresses of the visitors. Due to the use of a method known as IP masking, Google Analytics communicates information so that only a part of the IP address is used for geolocation, instead of the whole address. Google may disclose information to third parties where required by law or where such third parties process the information on Google’s behalf.
