internet protocols history?

[ali-maz]

Hello
I want to know information about older versions of the
ip v1- ip v2 ip v3 What is the difference between them and what is the domain of addresses in them and how much dedicated to the network addresses and how much dedicated to address the host and why they remain draft and why they were separated from tcp protocol
Has Cisco developed this protocol?
Thank you

Thank you
But I searched these pages previously and did not find an explanation of the size of bits assigned to the network and the host for the three old versions
