000023094 - Why Geoip database needs periodic upgrades

GeoIP database contains a mapping of IP addresses to global geographic locations. Over time the global geographic correspondence of  IP addresses changes. 

An IP address associating to one location may be reassigned to some other location through address re-assignment. IP address geographic correspondence can change through account removal or addition, or service provider changes. RSA On Premise Adaptive Authentication maps certain geographic locations to GOLDLIST, some to WATCHLIST or to BLACKLIST etc. Since the IP addresses are mapped to geographic locations through the GeoIP database, we treat those IP addresses according to their geographic associations. If the geographic correspondence changes and the database is not upgraded, an IP address might indicate an invalid location and may behave unexpectedly.

This is the reason why we need to stay current with the GeoIP database by periodic upgrades.Hence periodic upgrades of the GeoIP database are a best practice for production use.
