They get IP address information +from the RIRs, but the assignment changes regularly as some companies release +unwanted IP addresses and others obtain a new block of IP addresses. + +The blocks of IP addresses assigned to many companies can, in turn, assign them +to their users however they want without geographic boundaries. This makes +pinpointing geolocation of an IP address rather difficult. The accuracy of +geolocation data differs by provider. You can generally expect a 95% to 99% +accuracy for the country level. The more granular you get, the less precise the +data becomes. + +This projects downloads the information directly from the local RIRs and is as +accurate as the data provided. More often than not, the country attached to an +IP range is the one the registering company is located in. There is no reliable +way to determine the physical location of any IP without tracing it separately.
