Cross-border e-commerce platforms use IP addresses to assess the operating environment of accounts. Non-native IPs are easily detected as associated by platforms, leading to account throttling or bans. Native residential IPs are real home broadband IPs sourced directly from local ISPs, with extremely high anonymity. Platforms identify them as genuine local user environments, effectively preventing account association and significantly reducing the risk of bans, while also enabling precise access to local market data to improve store performance.
