IP Address Frequently Asked Questions

Answers to common questions about public IP addresses, geolocation, IPv4 and IPv6, dynamic addresses, VPNs, NAT, privacy, and network behavior.

What is my IP address?

Your IP address is the number your device or router uses to communicate on the internet.

Can my IP address reveal my exact location?

No. IP-based geolocation is approximate and is typically accurate to a city or region; it cannot pinpoint your exact street address.

What is the difference between IPv4 and IPv6?

IPv4 uses four decimal numbers separated by dots, while IPv6 uses hexadecimal groups separated by colons and provides a vastly larger address space.

Can I change my public IP address?

In many cases, yes. Dynamic ISP assignments can change, and a VPN or proxy can present a different address to websites.

Does restarting my router change my IP?

It depends on your ISP and address assignment. A restart can sometimes result in a different dynamic IP, but it is not guaranteed.

Can websites see my IP address?

Yes. A website or server you connect to can see the public IP used by the connection because it is needed to route the response.

Does a VPN hide my IP?

A VPN can cause websites to see the VPN server’s IP instead of your original public IP.

Is an IP address personal information?

IP addresses can be treated as personal data in some legal contexts when they can be linked with other information.

What is NAT?

Network Address Translation lets multiple devices on a private network share a public IP address.

Why do I have IPv4 but no IPv6?

IPv6 availability depends on the ISP and local network configuration.

Live network results can depend on your connection and third-party data providers.
