ResultValid IPv4 address
Address typePrivate address

Check on the spot whether an entered string is a validly formatted IPv4 or IPv6 address. For IPv4, it also identifies the address type โ€” private, loopback, link-local, or public. Everything runs in your browser; nothing is sent anywhere.

How to use

  1. Enter the IP address string you want to check.
  2. Whether it's a valid IPv4/IPv6 address, and its address type, are shown automatically.

FAQ

Can this tell me whether the IP address is actually in use?

No โ€” this tool only checks whether the string is correctly formatted. It cannot tell you whether that address is actually active on a network.

What is a private IP address?

The ranges 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 are reserved for private networks and aren't routed directly on the public internet โ€” commonly seen behind home routers.

Is the IP address I enter sent to a server?

No. All validation happens entirely in your browser's JavaScript; nothing is ever sent anywhere.
