There are more than a dozen commercial IP geolocation database providers, and the accuracy of each provider is different. 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.
