Your IPv4 address is checked with ipify.org, a free public service; nothing is stored by BTNI.
What this address is — and isn't
Your public IP address belongs to your internet connection, not to your computer or phone. Every device in your office or home usually shares it, because your router hands each of them a private address and does the talking to the internet on their behalf.
That's why the address your device shows in its own settings — often one beginning 192.168., 10. or 172.16. — is different. That private address only means something inside your own network.
IPv4 and IPv6 are two versions of internet addressing. Many connections have both; some only have IPv4. If one shows as “not detected”, your connection most likely doesn't use it — that's normal and nothing to fix.
The address can change. Most business broadband has a fixed (static) address; home, mobile and some business connections get a new one from time to time. A VPN shows the VPN's address instead, and on mobile data you'll see your network provider's address.
We show the address only to you. This page doesn't store or log it — see our Privacy Policy.
