Geolocation is the process of mapping IP addresses to specific geographical locations using latitude and longitude coordinates. It has various applications such as targeted advertising, fraud detection, content localization, digital rights management, network security, and analytics. However, geolocation accuracy can be compromised due to the distribution of IP networks, reassignment of IP addresses, and limitations of WHOIS records. Building a geolocation database involves extracting data from WHOIS records, interpolating information, and considering open source projects. The RIPE NCC, ARIN, and LACNIC databases provide geolocation support through attributes like geoloc and geofeed. However, the coverage of geolocation information varies across these databases.
