IPv6 address inspector

Validate an IPv6 address, see its expanded and RFC 5952 compressed forms, and its type — loopback, link-local, multicast, global and more.

Analyzed in this browser. Nothing is sent anywhere.

Accepts full and `::` compressed forms, an embedded IPv4 tail (`::ffff:192.0.2.1`) and an optional `%zone` suffix. Compression follows RFC 5952 (lowercase, longest zero run). IPv4 and IPv6 subnets/CIDR math are not covered — this page is a single address inspector.

How to use

  1. Enter an IPv6 address.
  2. See the expanded form, canonical compression, and type.
  3. Copy the compressed form.

What it supports

Accepts `::` compression, embedded IPv4 (`::ffff:192.0.2.1`) and a `%zone` suffix. A single address inspector — CIDR ranges and subnet math are not covered.
