The file sizes of the GeoIP2 Country, City, and Enterprise databases, and the GeoLite2 Country and City databases will increase significantly on Friday, August 20, 2021. The file size increase is due to the activation of a large number of IPv6 network ranges.

GeoIP2 Country
- Binary (MMDB): increase less than 1% to approximately 5.7 MB
- CSV IPv6 Blocks File: increase less than 1% to approximately 15 MB
GeoIP2 City
- Binary (MMDB): increase around 2% to approximately 126 MB
- CSV IPv6 Blocks File: increase around 8% to approximately 10.8 MB
GeoIP2 Enterprise
- Binary (MMDB): increase less than 1% to approximately 364 MB
- CSV IPv6 Blocks File: increase around 7% to approximately 160 MB

Update: The changes in file size were not as significant as initially forecast. We are working to establish processes that will allow us to provide better notification about a change in database file size.
