When I see myths propagated in the IETF, I try to correct them unless
someone else gets there first. For the trade rags it is really not
worth the bother. I was referring to RFCs, which is our output.

I was there. I was one of the members of the IPng directorate pushing to
copy the locator/identifier split, which is lacking in IPv4 and was
present in other datagram address formats of the same vintage. Please
don't tell me it was spin or a dishonest gloss. It was a design decision, and
one I stand by with no hesitation.

Dead on schedule. I've always said it would take 15 years.
