About this tool
Your public IP address is the address your internet provider, VPN or company network uses to reach websites. This page reads it from your connection to our server — no lookup service is involved — and shows whether it is IPv4 or IPv6 and its reverse DNS name.
Your address is used only to display this page. It is not stored with the result.
How to read the results
- IPv4 or IPv6 — which protocol your browser used to reach us. Many connections have both; browsers prefer IPv6 when it works.
- Reverse DNS — often reveals your provider, and sometimes your region.
- Registry — the regional registry that allocated the address block. Use the IP WHOIS lookup for the network owner.
Limitations
- With a VPN, proxy, Tor or iCloud Private Relay you see that service's address, not your connection's.
- Mobile networks and some ISPs share one public address between many customers (carrier-grade NAT).
- Only the address used for this connection is shown; if you have both IPv4 and IPv6, the other one is not tested.
Frequently asked questions
Is my IP address private information?
Every website you visit sees it. In the EU it counts as personal data, which is why sites must protect it. It generally reveals your provider and rough region, not your street address.
Why does my IP address change?
Most home and mobile connections get dynamic addresses that change when the router reconnects or periodically.
How can I hide my IP address?
A VPN or Tor routes your traffic through another network, so websites see that network's address instead.
What is the difference between public and private IP?
Private addresses (such as 192.168.x.x) are used inside your home or office network. Your router translates them to one public address for the internet.
Do you store my IP address?
It is not saved with the result or used for anything except showing this page.
Is my IP address IPv4 or IPv6?
The page shows which one your browser used.
