there were at least 4 candidates for IPng as I recall so this could account for assigning IPv6, IPv7, IPv8 and IPv9 but on final agreement, this left only the "next" unused protocol id, IPv6 to be assigned officially.<div>

<div>I have a recollection that the IAB had recommended a v7 prior to
the IPng process, and there was some strange proposal by an even
stranger person that had laid claim to v8, so v9 would have been next
in line. </div>

<div>If Ofer's recollection (?) is correct, there were other proposals
and so some numbers must be missing some place for that story to be
correct. </div>

<div>The early IAB proposal skipped v6, which is looking more and more
prescient in a weird sort of way.</div>

<blockquote>To clarify, what I recall is that the various candidates

before<br>
we knew which would be chosen, and the final choice - which turned

to be a hybrid - then got v6. For years we were talking about
"IPng".<br>
