(What happened, you might ask, to IPv5
? It did exist, but was never publicly deployed.)
Nigeria is a male dominated society where men are assigned more economic and political power and women are more dependent and this situation increases the risk of IPV5
. Despite the fact that women constitute half of the population, political appointments for women still fall short of the recommended 35% by the Beijing declaration (5).
This made it necessary to create a new protocol called IPv6 or also called new generation protocol, but if the change was from IPv4 to IPv6, what happened to IPv5
? Simply, IANA designated IPv5
as an experimental protocol called "Stream Protocol version 2 (ST-II)", the idea was to recognize an ST-II packet by observing the IP protocol version number: 4 was a normal packet and 5 was an ST-II packet, for this reason the new version is IPv6 and not IPv5
(There was also an IPv5
but it was not a successor to IPv4; rather, it was an experimental flow-oriented streaming protocol, intended to support voice, video, and audio.)
Internet Protocol version 6 (IPv6) quadruples the size of the address field from 32 bits to 128 bits (IPv1-IPv3, and IPv5
reportedly never emerged from testing in the laboratory).
The next logical replacement would be a 64-bit protocol, and one was created, IPv5
, but it existed solely in an experimental form.
Why, you may ask, is the new protocol not IPv5
? The version number 5 could not be used because it had been allocated to an experimental stream protocol.
