IP Address Info & Validator

About this tool

Check whether an IP address is valid, identify IPv4 vs IPv6, and see whether it falls in a private (LAN) or public range. (This works offline, it does not geolocate.)

Example

Input: 192.168.1.10

Output: IPv4, Class C, Private (LAN)

Privacy

This tool runs entirely in your browser. Your data is processed locally and never uploaded to a server.

How to use this tool

1. Paste or type an IPv4 or IPv6 address into the input field.
2. Click the check or validate button to analyze the address.
3. Read the result to see whether the address is valid, and whether it is IPv4 or IPv6.
4. Use the private or public label to tell if the address is a LAN address or an internet-routable address.

Step by step, what happens

1. The tool reads the address string exactly as entered and checks its format.
2. It verifies whether the value matches IPv4 rules or IPv6 rules, and rejects malformed input.
3. If the address is valid, it identifies the IP version and determines whether it belongs to a private range.
4. The result is shown instantly, and the tool does all of this offline without any geolocation lookup.

Worked example

For example, if you want to check a common home network address, you can test a private IPv4 value.

Input: 192.168.1.10

1. You enter 192.168.1.10 into the tool.
2. The validator recognizes it as a valid IPv4 address.
3. It marks the address as private because it is in a local network range.

Tips and common mistakes

• Use the full address, including all separators, because missing parts or extra characters will make the input invalid.
• Do not expect location or ISP details from this tool, because it only checks validity, IP version, and private versus public range.
• Private addresses such as 192.168.x.x, 10.x.x.x, and 172.16.x.x through 172.31.x.x are for local networks, not public internet use.
• If you are checking an IPv6 address, keep the colons in place and avoid adding spaces before or after the value.
