What is this tool?
My IP Address instantly looks up the public IP address of your current internet connection — useful for allow-listing remote access, diagnosing network issues, or checking your location. It looks up automatically on load; use Refresh to check again.
How lookup works
- IPv4: looked up via a free public API (ipify).
- IPv6: shown only if your network supports IPv6; otherwise left blank.
- Browser info: User-Agent, language, screen resolution, and timezone are read directly from your browser.
Privacy & processing
Looking up your IP calls an external API (ipify), and this page only displays the value it returns along with information your browser already exposes. Nothing is stored or separately collected by Calqu's servers, but note that your request is sent to ipify's servers during the lookup.
Why did IPv4 run out, and what does IPv6 solve?
IPv4 is a 32-bit system, capping the possible address space at roughly 4.3 billion. As smartphones and IoT devices pushed the number of connected devices far higher, newly assignable IPv4 addresses have effectively been exhausted for years. The fix is IPv6, a far larger 128-bit system now being deployed alongside IPv4. Because much existing equipment and networking still runs on IPv4, the two coexist during this long transition — if the IPv6 field here is blank, your ISP or network doesn't yet support it.
What's the difference between a public and private IP?
This tool looks up your public IP — the address your connection presents to the internet. Devices behind a home or office router (PCs, phones, printers) each get a separate private IP instead, in ranges like 192.168.x.x, 10.x.x.x, and 172.16.x.x–172.31.x.x, defined by the international standard RFC 1918. Private IPs only route between devices on the same router and never leave it directly; the router uses NAT to relay traffic for all of them through one public IP.
Why does my IP's estimated location not match where I actually am?
IP-based location isn't precise like GPS — it estimates a rough area based on the gateway or cell tower your ISP uses to manage that IP range. That often points to your carrier's regional hub rather than your exact location. If you're using a VPN or proxy, the location shown is that of the server instead, which can differ dramatically from where you really are.
