Was the IPv6 Mess predicted by IPv3, IPv4, and IPv5?
IPv4 ran out of addresses and IPv6 adoption has stalled... but did you know the protocol before IPv4 already solved the IP address limit, back in the 1970s? Speedify engineers explain why IPv6 adoption has struggled, how NAT became essential to IPv4, and why parts of the internet remain effectively stuck.
We explore the forgotten IPv5, the failed Internet Stream Protocol, and why modern replacements for TCP like QUIC and HTTP/3 are built on UDP instead of TCP. Also covered: what happened to IPv1–3, why IPv4 is only 32-bit, and how early design decisions still constrain today’s internet.
