Frequently asked questions

What is my IP address?

Your public IP address is the address websites see when you connect to them. It is assigned by your internet provider and shown at the top of this page.

What is the difference between IPv4 and IPv6?

IPv4 addresses look like 203.0.113.7 and are running out. IPv6 addresses look like 2001:db8::1 and provide vastly more addresses. Many connections have both.

How accurate is IP location?

Country is usually accurate; city is an estimate and can be off by tens of kilometres, especially on mobile networks or VPNs.

Can I get my IP from the command line?

Yes: run curl https://www.ferntool.com to get your IP as plain text, or curl https://www.ferntool.com/json for full details.
