IPv6 Packet Decoder

Decode the fixed IPv6 header, addresses, next-header value, and bounded payload from hex.

This tool handles input and primary processing in your browser and is designed not to send the input to QuickKit’s server.

Decoded fields

Remaining payload

How it works

Decode the 40-byte IPv6 base header and payload length. The next-header number is named when known, but extension-header chains are deliberately left in the payload rather than skipped without complete validation. A short declared payload is reported as truncated.
