Is IP Address Validator completely free?

Yes, completely free with unlimited validations. No registration, login, or payment required. All features are accessible immediately.

What's the difference between IPv4 and IPv6 addresses?

IPv4 addresses use 32 bits (e.g., 192.168.1.1) with 4 octets, supporting ~4.3 billion addresses. IPv6 uses 128 bits (e.g., 2001:db8::1) with 8 groups of hexadecimal digits, supporting 340 undecillion addresses.

Can I validate multiple IP addresses at once?

The tool validates one IP address at a time. However, you can validate unlimited addresses sequentially by clearing the field and entering new IPs—there are no usage limits.

Does IP Address Validator work on mobile devices?

Yes, works on all devices including iPhone, Android, iPad, and desktop browsers. The responsive design adapts to any screen size automatically.

Is my data safe when validating IP addresses?

Yes, completely safe. All validation happens in your browser locally. No IP addresses are sent to servers, logged, or stored—your data never leaves your device.

What information does the tool provide?

The validator returns validity status, IP type (public/private/reserved), CIDR notation, subnet mask, network range, broadcast address, first/last usable IP, and estimated geolocation data.

How do I know if an IP address is valid?

Valid IPv4 addresses have four octets separated by periods with values 0-255 (e.g., 8.8.8.8). Valid IPv6 addresses contain 8 groups of 1-4 hexadecimal digits separated by colons. The validator confirms format and structure.

What are private IP address ranges?

Private IPv4 ranges are 10.0.0.0-10.255.255.255, 172.16.0.0-172.31.255.255, and 192.168.0.0-192.168.255.255. Private IPv6 range is fc00::/7. These cannot be routed on the public internet.
