What's my IP address?

On a VPN or proxy, these are its exit addresses, not your device's. With both IPv4 and IPv6, your browser picks one for each site, usually IPv6; the big address is the one it picked here.

Network details come from Team Cymru's IP-to-ASN mapping, looked up over DNS. The network is whoever routes the address on the internet: your ISP, or your VPN or cloud provider.

Someone sharing a secret with you, locked to your IP? Send them this address, then open the link they send back in Secret Share.
