📖 Description
1. Why Do You Need an Online IP Lookup Tool?
In the complex internet environment, an IP address is the unique "ID card" of your device:
- Network Troubleshooting: Confirm whether your device has successfully connected to the internet, or if it has obtained an incorrect IP segment due to misconfigured routing.
- Geolocation Verification: Verify if your CDN acceleration node is assigned nearby, or confirm whether your cross-border proxy (VPN/Proxy) is active.
- Server Security Configuration: Quickly obtain the current public IP of your office or home to accurately configure Access Control Lists (ACLs) in server firewalls.
- Website Access Analysis: Developers can simulate requests from IPs in different regions to test a website's geo-restrictions or language adaptation features.
2. Core Feature Analysis
