Frequently Asked Questions
What is geofencing?
Geofencing creates a virtual geographic boundary. When an IP address enters or exits this area, specific actions can be triggered.
How accurate is IP-based geofencing?
IP geofencing is accurate to city level (25-50 miles radius). For precise geofencing, GPS or Wi-Fi positioning is needed.
What are geofencing use cases?
Common uses include content regionalization, ad targeting, security (blocking foreign IPs), compliance with regional regulations, and location-based access control.
What is the minimum radius for IP-based geofencing?
IP geofencing is typically accurate to 10-50 km in urban areas. For finer precision (under 1 km), GPS or Wi-Fi positioning is needed instead of IP-based methods.
How do content delivery networks affect IP geofencing?
CDNs route users through nearby edge servers, which can make IP geofencing detect the CDN server location instead of the actual user location. This affects accuracy for CDN-proxied traffic.
什麼是地理圍欄？
地理圍欄（Geofencing）是一種基於位置的技術，用於判斷設備是否在特定地理區域內。
常見用途：
• 驗證 VPN 連線是否成功切換到目標國家
• 檢查是否能存取特定地區限制的內容（如串流服務）
• 測試地區限制功能是否正常運作
