Hello Tero:

[Pascal] >> Do we need 20% of the subtypes for experimentations? 240 to 255
> seems enough to me…

> Most likely not, but if we have bit larger space allocated for them,[Pascal]  then people might not always take the first one...

> On the other hand, we do have 200 numbers for allocations, I think that is also enough.
[Pascal] We never know... but that's not my real issue

> If we ever get close to that number, I think we want to write the new RFC and specify the extension format of for the subtypes, and while doing that we can make the experimental use space smaller too.
[Pascal] Well, no. If people have a concern with 16 experimental values, and there is a lot of unallocated space, it is easy to allocate another range from the unallocated space. OTOH, you cannot easily give back from the experimental range, because there may be experiments using it that could collision with the new assignments. I'd rather allocate the extra experimental space from the 00 extension, and leave a maximum of space from the one-octet subtype for mainline RFCs as opposed to experiments...

Makes sense?

Pascal
