What Is My IP Address? IP Lookup Explained
Every device on a network has an IP address — but what is it, what does it reveal, and how do you check one? Here's a plain-English guide to IP addresses and lookups.
Look up an IP address
Paste any IP into the IP address lookup tool to validate it, see whether it's IPv4 or IPv6, and whether it's public or a private/reserved address.
Public vs private IPs
Your public IP is how the internet sees your whole network; your private IP (like 192.168.x.x) is used inside your home or office. Ranges starting 10.x, 172.16–31.x and 192.168.x are private and never appear on the public internet.
IPv4 vs IPv6
IPv4 addresses (like 142.250.72.14) are running out — there are only about 4.3 billion. IPv6 (like 2001:4860:4860::8888) has a practically unlimited supply, which is why the world is slowly migrating to it.
What your IP does and doesn't reveal
An IP can reveal your rough region and internet provider, but not your name, exact address, or what you're doing. It's more like a mailing area than a home address — useful for routing, limited for identifying a person.
