Primary Domain
Infrastructure
Within the Primary Domain facet, Infrastructure intelligence groups reporting by primary domain so readers can follow a focused area of internet infrastructure, governance, connectivity markets, or digital capital. The page brings together related articles, public evidence, institutions, companies, people, regional exposure, operating dependencies, and market context that may otherwise sit across separate category pages. It explains the domain, the likely actor class, the market or governance context, and the source material readers should use when comparing signals. Operators, analysts, and governance readers can see how the same domain appears across events, profiles, market shifts, public-source evidence, regional dependencies, and longer-cycle infrastructure decisions over time.

A Signature Is Not Proof of the Other Key: RFC 9883 and Private-Key Possession Statements
A second certificate request can be validly signed by an already certified signature key, yet that signature is only an assertion—not technical proof—that the requester controls the different private key behind the requested key-establishment certificate. RFC 9883 defines how a…

The Packet That Had to Answer Back: TCP's Challenge ACK Repair
TCP once treated a reset that landed anywhere inside the receive window as sufficiently believable to tear down a connection. RFC 5961 replaced that destructive shortcut with a narrower rule: exact sequence alignment could act immediately; merely plausible input had to survive a…

The ACK That Could Not Say Which Packet Arrived: Karn's Retransmission Ambiguity Rule
The same sequence range crossed the network twice. The acknowledgment that returned proved the bytes had arrived, but not which transmission had earned the reply. Karn's rule turned that uncertainty into a discipline: delivery evidence could advance while the round-trip estimator…

The Signature Algorithm Is Not the Signed Byte Sequence: RFC 9882 and ML-DSA in CMS
Two CMS systems choose ML-DSA-65 for identical content, yet verification fails when one signs a final implicit-tag representation and the other verifies the complete DER SignedAttrs value with its explicit SET OF tag. The algorithm is the same; the signed byte domain is not.
History
The Packet That Waited for Its Predecessor: Nagle's Small-Segment Rule
A one-byte write did not need a universal delay timer. It needed a rule about whether the connection already had data in flight. Nagle's answer made acknowledgment state—not the wall clock—the gate for another short TCP segment.

AfNOG Publishes Mailing-List Rules, Not the Moderation Procedure Behind Them
AfNOG’s mailing-list page sets clear expectations for a technical community: keep discussion operational, avoid disrespect, and do not use the list for blatant product marketing. The published page establishes the rules. It does not explain the procedure used when a post is…

A mobile-site generator is not a local continuity plan until refuelling access, runtime and restoration priority are verified
A generator beside a mobile site is equipment, not proof of continuity. The local capability begins only when the site’s real load, safe access, fuel replenishment authority, delivery time and restoration priority can be exercised as one bounded operating chain.

A Registry TTL Is Policy State, Not a Live DNS Observation
RFC 10037 lets a registry publish configured DNS time-to-live values through RDAP. That sounds like a small JSON extension. Its more important effect is to expose a piece of registry policy without pretending that a registration-data service is watching the live DNS. The…

A Data Model Is Not a Wire Contract: RFC 9880 and SDF Protocol-Binding Boundaries
Two implementations can claim the same Thing model yet disagree on the wire: one chooses a URL and JSON payload convention, while the other expects a numeric identifier and different invocation rules. The gap appears when a protocol binding was implicit rather than versioned and…

The Probe That Could Not Declare an Idle Peer Dead: TCP Keep-Alives
An idle TCP connection can be quiet without being broken. Keep-alive probing was designed to ask whether the peer's transport state could still answer, while denying any single unanswered probe the authority to declare that state dead.

A Hybrid SSH Key Exchange Turns Algorithm Negotiation into a Migration Boundary
Installing post-quantum code does not mean an SSH session used it. RFC 10042 defines three hybrid methods that combine ML-KEM with an established elliptic-curve exchange. The protection becomes real only when both peers offer the same method, negotiation selects it, both…

The Integrity Check Has Its Own Parameters: RFC 9879 and PBMAC1 in PKCS #12
A PKCS #12 exchange can fail at the integrity boundary when one implementation reads compatibility-shaped legacy fields while another follows PBMAC1’s nested parameters. The two sides can then disagree about the password-derived key, the MAC scheme, or the authenticated bytes.
