FAQ

Common questions

What is my public IP address?

Your public IP address is the internet-facing address assigned to your connection by your ISP, mobile carrier, VPN, or network gateway. Websites see this address when you connect.

Can this tool show Bisup or Vercel server IPs?

No. Bisup reads trusted request headers at the edge and returns the visitor address only. The API strips private, loopback, reserved and infrastructure addresses from responses.

Does this support IPv6?

Yes. The lookup engine recognizes IPv4 and IPv6, normalizes common proxy header formats and labels the address family clearly.

How accurate is IP geolocation?

IP geolocation is approximate. Country and ASN are usually reliable, while city and postal code may vary depending on ISP routing, VPNs, mobile networks and CDN behavior.
