IPv6 Toolkit

Parse an IPv6 address or prefix to see its canonical (RFC 5952) and fully expanded forms, special-use classification, prefix math, an EUI-64 MAC if present, and its ip6.arpa reverse-DNS name. Runs entirely in your browser.

IPv6 address or prefix

Parsing runs locally. The address never leaves your browser.
