AfNOG’s Reproduction-Permission Request Leaves the Licence Boundary Unstated
AfNOG’s 2007 call asked for permission to reproduce the contributor’s presentation after the event, including permission to post it on the AfNOG website. That sentence names two requested acts, but it does not state how long the permission would last, where it would apply…

ARIN’s Incoming-Reassignment Switch Makes Registry Association Consent-Bound
An organization identifier used to be available for an upstream provider’s reassignment workflow unless another requirement failed. Since ARIN’s January 2026 release, the recipient can refuse that association before it is created. The new switch changes registry accountability in…

The Root Writes the Shortcut: RFC 9914 Projects Routing State into RPL
A leaf-to-leaf packet may climb a stretched RPL DODAG path through the Root even when a shorter directional path exists. RFC 9914 lets the Root project a PCE-computed shortcut as routing state into selected nodes—improving path choice, but also making freshness, precedence…

The Number IPv4 Could Not Freeze: How the Protocol Field Became a Live Registry
IPv4 devoted one octet to a deceptively simple question: what protocol should receive the payload next? The answer could not live in the packet format alone. It required a shared assignment system that could change while the eight bits on the wire stayed fixed.

Cristiano Amon and Qualcomm's Two-Engine Bargain
Cristiano Amon's defining leadership test before becoming CEO was not simply to accelerate Qualcomm's chip roadmap. It was to keep product execution credible while a legally distinct licensing business faced customer conflict, litigation and regulatory pressure.

The Header Shrunk to One Octet. The Missing Bytes Moved into Shared State: RFC 1553
A packet crosses a slow link with a one-octet compression header. Its ordinary thirty-octet IPX header is absent. Nothing has been lost—if the receiver still holds exactly the right prior header in exactly the right slot. Let one earlier packet vanish, however, and the same…

Four Radios, One Control Problem: What RFC 9913 Reveals About RAW's Capability Plane
Four radio technologies can each advertise scheduling or redundancy while exposing different clocks, resource units, diversity primitives and failure correlations; their feature names are therefore not interchangeable assurance promises. This briefing by Theo March examines how…

AfNOG’s Affiliation Field Names an Institution Without Defining the Relationship
AfNOG’s 2007 call requested a contributor’s affiliation without defining what relationship that label represented.
History
Why IPv4 Checksums Only Its Header
A packet can carry an undamaged payload and still be dangerous to forward if a bit error changes its destination, length or remaining lifetime. IPv4 therefore checks the control surface routers must trust: its header, and only its header.

Barry’s README Uses the IPv6 Prefix Its Lexer Rejects
`::/0` and `0::/0` name the same IPv6 address space. In LACNIC’s experimental Barry generator, the first spelling is documented as a default yet an open issue says it stops at the descriptor lexer; adding one zero lets the token proceed. That is not an RPKI validation failure. It…

The Reference Was Well-Formed. It Was Not Yet Evidence
A digest can look precise enough to end an argument. Revision 03 of the Canonical Payload Binding draft instead turns that apparent certainty into a sequence of accountable tests: the reference must be admissible, one authorized digest context must be selected, the artifact must…

The Fast Path Is a Recovery Graph: RFC 9912 Moves Wireless Reliability Into the Network Plane
Wireless conditions can change faster than a controller can install a new route, so RAW preinstalls a finite recovery graph and lets a Point of Local Repair select protection paths locally. That is the architectural move: reliability becomes a network-plane control problem, not a…

The Maximum Metric Kept the Link. Missing Data Could Keep It or Remove It
A routing value can look catastrophic without withdrawing a link, while an empty field can either remove that link or leave it eligible. RFC 9843 makes those outcomes deliberate. Operations fail when telemetry turns three different protocol states into one red icon.

A RISC-V Profile Is a Compatibility Vocabulary, Not a Hardware Mandate
A RISC-V profile makes a useful promise of language, not a universal promise of hardware. It tells hardware and software communities which bounded instruction-set surface they can discuss together. It does not, by itself, tell a buyer what is on a particular chip, tell a…

Vint Cerf and the Deadline Behind the TCP/IP Cutover
The decisive test was not whether TCP/IP worked in a document. In Vint Cerf's recollection, rehearsed NCP shutdowns in 1982 exposed mail disruption and showed how much operational work remained before the ARPANET could change protocols. The transition became credible through…

The Namespace Stayed Put: RFC 9911 Makes Common YANG Types a Migration Surface
A server can import the same `ietf-yang-types` namespace yet validate a timestamp differently when the common module revision changes. RFC 9911 keeps the familiar module identity while revising accepted values, canonical forms, and descriptions—turning a shared typedef library…
History
When IPv4 TTL Stopped Being a Clock
IPv4 gives every datagram a field called Time to Live, measured in seconds. Yet the forwarding rule subtracts at least one even when less than a second has passed. That mismatch turned a nominal lifetime timer into the Internet's practical hop budget.

The Formatting Could Disappear. The Message Still Had to Be Readable: RFC 1523
A reader that understood no boldface, centring or indentation could still recover the prose. RFC 1523 made that outcome a property of the format itself: presentation commands were disposable, while their limits, nesting and whitespace rules made the remaining text predictable…

AfNOG’s Direct-Contact Field Lists Reachability Without Stating Its Handling Boundary
AfNOG’s 2007 call requested four published contact points without publishing an adjacent purpose, access or retention notice.

The Link Is a Snapshot: RFC 9910 Makes RIR Hierarchies Searchable
A single-result RDAP search link may become a lookup URL, but registry state can change before a client follows it. The link is therefore a time-bound snapshot of a registry view, not a timeless statement about a resource.
