The terms Internet and World Wide Web are often interchanged, yet they are not the same. The Internet is a global system of interconnected computer networks while the World Wide Web is one of the services transferred over these networks. It is a collection of text documents and other resources, linked by hyperlinks and URLs, usually accessed by web browsers from web servers.

An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, server) participating in a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there." In the United States, nearly 1.5 billion IP addresses have been allocated to internet service providers of which 10-15% are active at any specific moment.

The diagram demonstrates how the typical person accesses different IP addresses throughout their day. For example, as they start the morning from home they might use their personal PC (7am – 8:30am); utilize their smart phone at work (9am – 5pm); and their laptop afterwards.

Internet Protocol (IP) geolocation methods estimate the geographic location of an Internet host (IP address) using various information sources on IP addresses. Such geolocation data can include information such as continent, country, region, city, latitude, longitude, time zone and other unique identifiers. Currently available IP geolocation products and services provide results with significant inaccuracy and do not cater for the evolving dynamic environment.
