How to use it Your public address is shown first. To find out who owns another public address, type it into the box and look it up.
Your public IPv4 address
216.73.216.59
This is the address websites see when you visit them. If you are on a VPN or a work network, it is the VPN’s or the company’s address, not your device’s.
We do not store your address. The owner lookup only runs when you press the button: it asks Team Cymru’s public IP-to-ASN service (a DNS lookup from our server) which network the address belongs to.
