AFRINIC's First Article 24 Text Now Needs Its Own Review
The deadline passed at 23:59 UTC. In the 53-page constitutional draft still linked the next day, Article 24 had a heading, a number and a promise to add the law and dispute route later—but no clause for entities to review.

DMTF: The Standards That Control Servers Below the Operating System
A server can be powered off, inspected, updated or reconfigured even when its operating system is unavailable. DMTF defines much of the language used for that privileged management plane, from Redfish APIs and MCTP transport to PLDM commands, SPDM identity and SMBIOS inventory.…

DMTF and the Language of Server Management
A server can be powered off, inspected, updated or reconfigured even when its operating system is down. DMTF defines much of the language of that privileged management plane: from the Redfish API and MCTP transport to PLDM commands, SPDM identity and SMBIOS inventory. Common…

The Sum That Had Two Zeros: How the Internet Checksum Bounded Error, Not Trust
The Internet checksum made damaged packets easier to reject by making a deliberately small claim. Its strangest corner case—two representations of zero—shows why even cheap evidence must preserve an exact boundary.

One Document Store Put Five RIPE NCC Workflows on Hold
A resource transfer can wait because a policy question is unresolved, because evidence is incomplete, or because the filing cabinet is being upgraded. On 22 August, RIPE NCC members encountered the third case. The distinction matters: a planned administrative pause is not a…

The Report the Sender Could Not Trust: Why TCP SACK Remained Advice
A TCP sender may keep a byte range in memory even after the receiver has explicitly reported it. That apparent distrust is the safeguard at the centre of selective acknowledgment: a precise observation can guide recovery without becoming a final receipt or a command.

Cloud Portability Has a Postcode
Cloud computing was sold as locationless infrastructure, but the economics of leaving it are becoming conspicuously geographic. Within the same hyperscaler, the rights and price attached to moving data can now turn on account country, billing address, source region, network path…

LACNIC's Legacy Deadline Is Running Ahead of Its Policy
Prior BTW reporting describes legacy IPv4 holders answering an administrative request while the community rule that would govern the same evidence is still being debated. That sequence does not make the outreach illegitimate. It makes the label on every decision unusually…
History
The Acknowledgment That Learned to Point: How TCP SACK Made Loss Visible
TCP's original acknowledgment could certify an unbroken prefix of a byte stream, but it could not describe the islands waiting beyond the first gap. Selective acknowledgment added a small map of those islands while leaving the sender—not the receiver—in charge of repair.

The Router That Pointed Sideways: How ICMP Redirect Stayed Local
ICMP Redirect let a gateway reveal a better local next hop without becoming a routing authority. Its power ended at the host that had just used it.

The Number That Became Newer After Zero: How DNS Ordered Versions Without a Clock
At the edge of a 32-bit counter, DNS asks operators to accept an apparent impossibility: zero may be newer than 4,294,967,295. That rule let independent name servers agree on version order without sharing a clock, but only inside a deliberately bounded window.
Story
The Evidence ARIN Should Require Before Retiring Legacy Whois
ARIN's new directory-services consultation looks like a consolidation project. Its migration inventory tells the more important story: an API can announce its own retirement, a local reassignment server needs a conversion tool, and Port 43 can hide inside scripts that the…
History
The Zone That Knocked: How DNS NOTIFY and IXFR Cut Staleness
DNS once made every secondary wait before learning its authority was stale. In 1996, NOTIFY delivered the knock and IXFR carried only the edit.
History
The Address You Needed DNS to Find: How Glue Broke the Delegation Loop
A DNS referral can name the server that knows the answer and still leave a resolver unable to reach it. Glue was the small, deliberately non-authoritative exception that let the resolver cross that gap without giving the parent zone control over the child's facts.
History
The Address That Asked the Wire: How ARP Made Local Reachability Revisable
Routing can choose the next IP address without knowing how to put a frame on the local cable. ARP filled that last gap with a public question, a private answer, and a memory designed to be corrected.

APNIC's /12 Reserve Turns a /22 Offer Into a Queue
The newest impact assessment for prop-168 starts with a subtraction. APNIC counted 11,729 `/24` units in hand; protecting a `/12` for future transition use would remove 4,096 of them, leaving 7,633 for a wider group of applicants whose combined maximum demand would be larger.
History
The Connection That Had to Prove It Was New: Why TCP Needed a Three-Way Handshake
A packet can arrive at the right address, carry a plausible number and still belong to a conversation that has already died. TCP's familiar opening exchange was designed around that ambiguity: before accepting a new connection, both endpoints must show that they have seen each…

An IRU Buys the Strand, Not the Road Around It
A dark-fibre contract can name a strand, reserve it for twenty years and make it feel like an owned asset. The harder question begins one layer out: who controls the ducts, access, power, maintenance, relocation and remedies that keep that strand useful when the route changes or…

The Packet That Had to Learn Its Size: How Path MTU Discovery Moved Fragmentation to the Edge
A packet may cross a path whose narrowest link is invisible to its sender. The Internet spent four decades changing who should discover that limit, who should report it and who should decide what size to send next.

AFRINIC's New Committee Has Five Votes and Three Expiry Dates
AFRINIC has filled a governance body with five voting members chosen through two different routes. The more important design feature may be the calendar: its seats do not all expire together, and its advice cannot bind the people who receive it.
