Key Insights

• 💨 RFCs originated as a way to gather comments and feedback on internet standards proposals.
• ❓ TCP/IP and other important internet protocols rely on RFCs for their development and standardization.
• 🤑 There are serious, informative RFCs, but also humorous ones, sometimes published on April Fools' Day.
• 👥 The RFC process involves working groups, drafts, and iterations before finalizing a standard.
• #️⃣ RFC numbers are generally sequential, but exceptions can be made for specific reasons.
• 🥺 The issue of running out of IPv4 addresses led to discussions and proposals, including IPv6.
• 😒 Implementing humorous RFCs, like transmitting TCP over pigeons, is not recommended for practical use.

Questions & Answers

Q: What was the purpose of the first RFC?

The first RFC, published by Steve Crocker, sought feedback on proposed internet protocols and standards.

Q: How do comments on RFC drafts work today?

Comments on RFC drafts are typically submitted by working groups, who suggest revisions, add features, and engage in discussions.

Q: Are all RFCs serious and standard-setting?

No, some RFCs are humorous or even satirical. Examples include RFC 1149 on transmitting IP datagrams over avian carriers (pigeons).

Q: How are RFC numbers assigned?

Most RFCs follow a sequential numbering system, but some receive special numbers for specific reasons, such as replacing an entire standard.

Summary & Key Takeaways

• RFCs (Request for Comments) started as a way for early internet pioneers to gather feedback on proposed standards.

• All internet standards rely on RFCs; examples include TCP/IP, RFC 793 and 791.

• RFCs are published as drafts, with comments and revisions made by working groups before finalization.
