IP Geolocation vs. GPS: How Does a Website Know Where I Am?
The most repeated question many users of internet answer as they surf the net is how does a site know my location. This query is usually asked in cases where the site is displaying local content, services that are located in the area or a result that is determined by geography. Some of the technologies used by websites to estimate the location of their users may either be executed in the background or with permission of the user.
The two are the IP-based location detection and the GPS-based location detection. The purpose of each of the methods is different, as well as the degree of accuracy is different. Understanding how these systems work helps users know how websites identify your location and what information is being shared.
Method 1: IP-Based Geolocation
IP-based geolocation is one of the most popular techniques of detection of location. Each and every device that is connected to the internet has been allocated an IP Address by its internet service provider. This unique code acts like a digital fingerprint, often leading users to ask, "what is my IP address?" This address is a network identifier and not physical address.
As one visits a site, this identifier is automatically sent to the site. It is then compared to the large databases maintained by the site which associates the IP ranges with geographic locations. This approach will provide a rough sense of location, which typically will be at the country or city level.
IP-based identification does not require permission. It assists websites in understanding where am I in a general sense. It is frequently utilized by businesses to select language, regional content, prevent fraud and basic analytics. Nevertheless, it is not able to give precise positioning and movement in real time.
Method 2: GPS and Browser Geolocation
To be more specific, websites use geolocation capabilities of browsers and GPS-based. The latest technology is able to identify whereabouts through the satellite signals, Wi-Fi networks, and mobile towers. The procedure results in specific GPS coordinates which indicate a precise location in a map.
This is in contrast to the IP-based detection which involves user consent. Each time a site requests entry, a permission pop-up is shown in the browser. It is only then, after clicking on the "Allow" button that the site discerns your current Location with high accuracy.
This technology is usually referred to as navigational, delivery tracking, local search results, and map services. It is an accurate and reported response to queries based on location, which only works on the condition that users provide their information.
Conclusion
It is through various technologies that websites learn location based on the accuracy requirement and with the consent of the users. IP-based detection provides fast and rough estimate without authorization. GPS-based detection will be of a detailed and accurate result but must be approved.
The two methods assist websites in providing more relevant and better services. Knowing the way they operate provides the users with greater control over their online experience. The above tool will show you your position in real time and how your browser is sharing information.
