IPv6 Validator
Validate IPv6 addresses and verify their format. Check addresses in full, compressed (::), or mixed notation. Get detailed information about the address type and scope.
Enter an IPv6 address to validate and analyze. Supports compressed (::) notation.

Frequently Asked Questions
What is a valid IPv6 address?
A valid IPv6 address consists of eight groups of four hexadecimal digits separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). Groups of consecutive zeros can be compressed using :: notation, but only once per address.
What is the :: compression in IPv6?
The :: notation represents one or more groups of consecutive zeros. For example, 2001:0db8:0000:0000:0000:0000:0000:0001 can be written as 2001:db8::1. You can only use :: once per address to avoid ambiguity.
Does it support IPv4-mapped IPv6 addresses?
Yes, the validator supports mixed notation like ::ffff:192.168.1.1, which represents an IPv4 address mapped to IPv6 format. This is commonly used in dual-stack environments where both IPv4 and IPv6 coexist.
What are the different IPv6 address types?
IPv6 addresses include several types: Global Unicast (2000::/3) for internet-routable addresses, Link-Local (fe80::/10) for single-segment communication, Unique Local (fc00::/7) similar to IPv4 private ranges, Loopback (::1) equivalent to 127.0.0.1, and Multicast (ff00::/8) for one-to-many communication.
Is this IPv6 validator free to use?
Yes, this tool is completely free with no signup required. All validation happens in your browser — no data is sent to any server, keeping your network information private and secure.
