IPv5: Did it exist between IPv4 and IPv6?

After IPv4 was IPv6 -- why wasn't there ever a v5?

There actually was a v5. It was assigned to an experimental protocol which never came to life. Therefore the number was used and the number 6 was assigned to the next generation IP, which in the early days was called IPng.
