IP-based geolocation is a technique used to determine the real-world geographic location of the device through which you are connected to the Internet. This means that each IP address or range of IP addresses must have a record of its location, such as its address, city, country, operator/manager, among others.
All IP address ranges assigned in Latin America and the Caribbean are registered in the LACNIC database and can be queried through the whois service. More information: http://www.lacnic.net/1002/1/lacnic/whois
Many websites and online services must be able to identify where their visitors are located, either to display the website in the user's native language, automatically fill in online forms, or produce better search results based on the user's location. It is also essential to increase the security of online services, as it offers e-commerce operators the chance to reduce fraud or restrict access to their services to certain countries or regions.
Every day, LACNIC publishes a list of all assignments and sub-assignments made in the Latin American and Caribbean region. This publication is available for download at the following links:
