 That is a decidedly bad decision.

 There is no IPv5.

There is, but experimental, not finished, abandoned.
It doesn't even have an Wikipedia page. There is one Spanish, though:

IPv5
IPv5 is version 5 of the Internet Protocol (IP) defined in 1979 and which did not go beyond the experimental level. It was never used as a version of the Internet Protocol.
The version number ‘5’ in the IP header was assigned to identify packets carrying an experimental protocol, which was not IP, but ST. ST was never widely used and as version number 5 was already assigned, the new version of the IP protocol had to stick with the next identifier, 6 (IPv6). ST is described in RFC 1819.

Internet Stream Protocol
The Internet Stream Protocol (ST) is a family of experimental protocols first defined in Internet Experiment Note IEN-119 in 1979,[1] and later substantially revised in RFC 1190 (ST-II) and RFC 1819 (ST2+).[2][3][4] The protocol uses the version number 5 in the version field of the Internet Protocol header, but was never known as IPv5. The successor to IPv4 was thus named IPv6 to eliminate any possible confusion about the actual protocol in use.
