The geolocation of the network is determined by specialised services such as MaxMind, ipinfo and so on. Some of them are updated every 2 weeks, others once a month.
Geolocation is determined by a country which is listed in the RIR and where the network is announced from. If you want to announce a network in a specific country, please contact our team. We will send requests to the necessary services and change the country in the RIR.
