Sesame, salt, and substance. A flagship bake.
Summary
This article explains why IPv6 is more complex than IPv4 and addresses common misconceptions about simpler alternatives. It argues that IPv6's complexity stems from fundamental design requirements that couldn't be solved by simply extending address length, and that proposals for simpler alternatives (often called "IPv8") are misguided and waste time. The article provides technical reasoning for why IPv6's design decisions were necessary for modern networking needs.
Key quotes
· 4 pulledThere's no question that IPv6 is more complicated than IPv4, and people sometimes ask why that is.
Surely it would have been much simpler to just add an extra 32 bits to the IPv4 address, and change nothing else?
This note attempts to answer the question, and to show why such proposals are a waste of everybody's time, especially for the people who propose them.
every year or two people propose alternatives to IPv6 ('IPv8' is a generic name for such proposals, which mainly involve 8-byte addresses) because they have asked themselves that question.
