Struggling with Inconsistent Geolocation Data for Specific IP Ranges in Our New Lookup Tool

Hey everyone, we recently launched our IP lookup tool and it's been pretty solid overall, but we've noticed some really inconsistent GeoIP data, especially for certain obscure IP ranges. This inconsistency is causing headaches, and we're trying to figure out the best way to improve the accuracy of our geolocation results. Does anyone have recommendations for highly reliable GeoIP APIs or specific best practices they use to ensure more accurate IP geolocation? Thanks in advance!
