Proposal for the 'evil bit', as an option in the IPv4 packet header. Later, this became a synonym for all attempts to seek simple technical solutions for difficult human social problems which require the willing participation of malicious actors.
Notable for containing PDP-10 assembly language code nearly 22 years after the manufacturer ceased production of the PDP-10, and for being technically possible as opposed to many of these other proposals.
An April 1st RFC was not published this year, but an announcement on the IETF list about the appointment of the Sesame Street character Bert as member of the IAB appears to have been the April Fools' Day 2006 stunt.
When it becomes possible to send packets over the Internet faster than light, they may be received before they are sent (due to time reversal), which will have major impact on many protocols in use today. With sufficient speed (and corresponding negative time shift), a complete communication may have taken place before it even has started. The RFC reviews the design principles of those protocols, to prevent future breakdown of communication. Most likely, we should have started upgrading them yesterday.

Although generally unwanted, private key counterparts of X509digital certificates may have been or have been shared with a third party, for lawful interception or other reasons. Users may now be notified of this fact with a new certificate extension, specifying the boolean value ext-KeyUsage. When 'true', the private key has been shared; when 'false', the signer abstains from commenting on whether or not sharing has taken place.
Green IT has become increasingly important. In a win-win proposition, for packets and the environment alike, this RFC defines a way to allow packets to be routed through the air, to get as much sunlight and fresh air possible. Sending packets over Wi-Fi or by pidgeons will help them escape their torturous routine of assembly and disassembly, and being shot through dark fibers and copper cables all the time.
M. Luckie (1 April 2015). Really Explicit Congestion Notification (RECN). Independent Submission. doi:10.17487/RFC7514. ISSN2070-1721. RFC7514. Experimental.An RECN message SHOULD be sent by a router in response to a host that is generating traffic at a rate persistently unfair to other competing flows and that has not reacted to previous packet losses or ECN marks.
In an approach similar to the now deprecated ICMPSource Quench, it reuses that packet's 'Type' field (4) to tell the sender (really more explicitly than ECN) to shut up. The user responsible for the traffic MUST be made aware of the contents of an RECN message by means of text-to-speech, or pop-ups if the audio channel is muted.
Takes a rather mathematical approach to use the 128-bit IPv6 address space in other ways than the traditional one, to ultimately arrive at Complex Addresses. You may use the imaginary part of a complex address (with polar coordinates as the real part) to reach Santa Claus, for example. It also proposes to use Flying Addresses for end hosts using IP over avian carriers.
As the Internet Architecture Board intends to relax requirements for compatibility with IPv4 for new or extended protocols, this RFC helps the adoption of IPv6 by setting the evil bit for all IPv4 packets to 1, making sure that dual stack hosts will favor IPv6, as will the Happy Eyeballs algorithm. To maintain functional equivalence between IPv4 and IPv6, the 'security flag' of RFC3514 should be included in the IPv6 header. Advanced security options may be specified in a new hop-by-hop option header.
A heartfelt cry to end packet discrimination at the IP level, where they frequently (even in this day and age) are terminated prematurely, based on color,[5]length, age, etcetera, or even by IP version!
Proposes to use 128-bit Unicode to facilitate internationalization of IPv6, since the 1.114.112 code points of the current implementation of Unicode is deemed insufficient for the future. IPv6 addresses may be represented by a single U+128 glyph, to reduce stress on the eyes of network administrators.
If implemented, it would obsolete RFC8135, because "[i]t was found to be too complex to implement anyway".
A 'response/request' protocol similar to HTTP/1.1 but where clients send a response to the server (e.g. "Hello World. My payload includes a trailing CRLF.") to which the server answers with a request (e.g. GET /hello.txt), like in the Jeopardy! game. The Hypertext Double Jeopardy Protocol (HTJ2P) (described in Appendix A) inverses the semantics of HTJP again.
A proposal to use UTF-8 to obfuscate (and help replace) textual IP addresses, to coerce a small minority of people to use the DNS instead of sticking to (and mixing up) plain IP addresses.
Dismisses RFC6921 with the notion that considering time travel for faster-than-light packet delivery is "amusing" but impossible as a concept. Instead, it focuses on real life quantum entanglement in relation to packetround trip times, which (depending on the observer) could reach zero. This may cause havoc among several protocols, which should be fixed "in time" before things break.

Since the Internet Engineering Task Force claims it "is not the Protocol Police", it is formally established here. It polices various aspects of protocol definitions laid out by the RFC series, and enforces adherence to them. They are sanctioned to access walled gardens and may even resort to traffic imprisonment. By the way: if you are interested in joining the Protocol Police, contact your localhost.
Discourages the practice of introducing software defects, to reduce costs and lessen security impacts. By introducing some best current practices the authors hope to get rid of them: "Authors MUST NOT implement bugs. If bugs are introduced in code, they MUST be clearly documented."
Known problems with hexadecimal representation of numbers can be avoided by replacing its alphabet of 0-9 and A-F with two octal ranges: 0-7 and the letters 'cjzwfsbv' (to represent values 8-15 in a bitwise elegant way).
As is customary in light novels, a 'death flag' indicates the increased likelihood of a swift demise of the character. Transferred to TCP, the DTH flag in the packet header could lead to smoother and more attractive session narratives.
Finally, a formalized way (with a ABNFgrammar description) to properly describe the interaction between cats and containers, including the occasional ball of yarn.
The AI Sarcasm Detection Protocol (ASDP) is a framework for detecting sarcasm in AI systems (written with the help of ChatGPT). Detecting sarcasm may help improve AI - human intercommunication.
The recent advances in artificial intelligence (AI) such as large language models enable the design of the Faster than Light speed Protocol (FLIP) for Internet. FLIP provides a way to avoid congestion, enhance security, and deliver faster packets on the Internet by using AI to predict future packets at the receiving peer before they arrive. This document describes the protocol, its various encapsulations, and some operational considerations.
A poem that discusses problems that arise, and debugging techniques used, in bringing a new network into operation. It shows that array indexing is problematic since the olden days.
The RFC Editor accepts submission of properly formatted April Fools' Day RFCs from the general public, and considers them for publication in the same year if received at least two weeks prior to April 1st.[6][7] This practice of publishing April Fool's Day RFCs is specifically acknowledged in the instructions memo for RFC authors, with a tongue-in-cheek note saying: "Note that in past years the RFC Editor has sometimes published serious documents with April 1 dates. Readers who cannot distinguish satire by reading the text may have a future in marketing."[6]
