What Are RFCs and Why Should I Care?

Introduction

So, you’ve stumbled upon the term RFC and are wondering, “Is this some secret code? A new texting acronym the kids are using?”

Fear not! Let’s dive into the world of RFCs, uncover their origins, and see why they matter.

A Brief History of RFCs

Back in the groovy days of 1969, when bell-bottoms were in vogue and the internet was just a twinkle in ARPANET’s eye, a visionary named Steve Crocker introduced the concept of Request for Comments (RFCs). (en.wikipedia.org)

These documents started as informal memos among researchers, a way to share ideas, propose protocols, and, well, comment on each other’s work without the rigidity of formal standards.

Fast forward to today, and RFCs have become the backbone of internet standards.

Managed by the Internet Engineering Task Force (IETF), they serve as the official record for protocols, procedures, and conventions used on the internet.

But remember, while some RFCs lay down the law (like defining HTTP or SMTP), others are more like friendly suggestions or experimental musings.

RFCs: Proposals, Not Laws

Think of RFCs as the internet’s brainstorming sessions.

They’re proposals open for discussion, debate, and improvement. Just because an RFC exists doesn’t mean it’s set in stone.

It’s more like saying, “Hey, here’s an idea. What do you all think?” This collaborative approach has allowed the internet to evolve organically, adapting to new challenges and technologies.

Notable RFCs: The Serious and the Silly

The RFC series is a treasure trove of both groundbreaking protocols and delightful humor. Let’s explore a mix of both:

1. RFC 821: Simple Mail Transfer Protocol (SMTP)

   • Description: Defines the protocol for email transmission.
   • Link: RFC 821

2. RFC 2616: Hypertext Transfer Protocol (HTTP/1.1)

   • Description: Specifies the HTTP/1.1 protocol used for web communication.
   • Link: RFC 2616

3. RFC 2324: Hyper Text Coffee Pot Control Protocol (HTCPCP/1.0)

   • Description: An April Fools’ joke specifying a protocol for controlling coffee pots.
   • Link: RFC 2324

4. RFC 7168: The Hyper Text Coffee Pot Control Protocol for Tea Efflux Appliances (HTCPCP-TEA)

   • Description: An extension to HTCPCP to allow communication with teapots.
   • Link: RFC 7168

5. RFC 1149: A Standard for the Transmission of IP Datagrams on Avian Carriers

   • Link: RFC 2549

7. RFC 748: Telnet Randomly-Lose Option

   • Description: Proposes a Telnet option to randomly lose data, satirizing network unreliability.
   • Link: RFC 748

8. RFC 3251: Electricity over IP

   • Description: A humorous take on transmitting electricity over internet protocols.
   • Link: RFC 3251

9. RFC 1925: The Twelve Networking Truths
