From IPv4 to IPv6
Built up to the IPv6 specification that we have today using various proposal submissions such as:
- ISO CLNP– demonstrated as TUBA (TCP and UDP over Bigger Addresses)
- IP version 7 (aka TP/IX, RFC 1475)
- IP in IP – evolved to IP address encapsulation
- PIP – merged into SIP creating SIPP
(RFC 1710)
