IP location is approximate and may reflect your ISP, mobile carrier, VPN exit node, proxy, or data center rather than your exact physical location.
Start with the IP address the service can see
Local network settings do not always match the public address visible to a website or API. Before escalating a support ticket, check the public IP with VPN on and off, then note the network, browser, time, and exact error message.
VPN exit IP
A VPN may show a different city, country, or data center IP than your home or office network.
API allowlists
If a provider allows only known IPs, a changed public IP can trigger access errors even when credentials are correct.
Proxy and office networks
Corporate networks may route traffic through shared gateways, security tools, or regional proxy infrastructure.
Support evidence
A clear support request includes public IP, time, network type, VPN state, endpoint, and exact error message.
A practical IP troubleshooting workflow
1. Check IP with VPN off
Record the visible public IP from the normal network before changing anything.
2. Check IP with VPN or proxy on
Compare the new visible IP and location hints with the first result.
3. Test another network
Try mobile hotspot or another Wi-Fi network to see whether the block follows the account, device, or network.
4. Share a concise support note
Include IP, timestamp, timezone, VPN state, service URL, and a redacted error message or request id.
Check the visible public IP first
Use the IP tool to copy your public address and basic network details. Then compare the result across VPN, proxy, hotspot, and normal Wi-Fi.
Check my IP常见问题
Why does my IP location look wrong?
IP geolocation is approximate and may reflect your ISP, carrier, VPN provider, proxy, or a nearby routing point.
Can a VPN break API access?
Yes. Some APIs, SaaS tools, and dashboards use IP allowlists, fraud checks, region rules, or firewall policies.
What should I send to support?
Send your public IP, VPN state, network type, timestamp, timezone, affected URL or endpoint, and the exact error text with secrets removed.
