I think that I finally got it: 0x7E to 0x7F is for just experimentation. 0xFE to 0xFF is for shim headers experimentation My confusion came from the fact that is not clearly stated. Can we modify the text as: 0x7E to 0x7F: Experimentation and testing 0x80 to 0xFD: Unassigned (shim headers) 0xFE to 0xFF: Experimentation and testing (shim headers) So that the difference is clearly stated.

As you may remember shim headers have a more fixed encodng and must be located before non-shim headers. That is OK for me. But my question is why this: 0x7E to 0x7F: Experimentation and testing FM> The two above are for experimentation of NON shim headers 0x80 to 0xFD: Unassigned (shim headers) 0xFE to 0xFF: Experimentation and testing FM These two are for experimentation of shim headers. Shim headers are placed (and processed) first, so we want to give the freedom to experiment with both. For example, one would want to experiment with a shim header (identified by 0xFE) that carries some special metadata for IPv4 payloads, while someone else would want to experiment with IPv8 payloads (identified with 0x7E). A third person might want to experiment, at the same time, with a shim header that carries special metadata for IPv8. Fabio Instead of this (range has been adapted): 0x7E to 0xFB: Unassigned (shim headers) 0xFC to 0xFF: Experimentation and testing ?? Certainly I am missing something ;-) Ciao L.

Looking at the next protocol values we now see: 0x7E to 0x7F: Experimentation and testing 0x80 to 0xFD: Unassigned (shim headers) 0xFE to 0xFF: Experimentation and testing Can you provide a rationale why not having just one bigger experimentation and testing range instead of two with an unassigned range in the middle?
