Is it possible to calculate the country by IP address without using third-party services?

Question

Geolocation

When entering the site, we collect statistics, including the IP address. Further, using this IP address, we determine the user's country and display statistics by country.
To determine the country, we make requests to ipinfodb.com. There are a lot of visitors and from time to time most of the data is not loaded. Apparently, there are some restrictions and limits for this service.
Is it possible to determine the user's country without resorting to third-party databases?
