Lead Report / History

A bankruptcy court order page lying beside two open registry ledgers, one showing a point-of-contact line struck through and rewritten, linked by a steel pen on a polished table.
On 26 April 2011 a Delaware bankruptcy judge authorised Nortel Networks Inc. to sell roughly 666,624 legacy IPv4 numbers to Microsoft. The order settled liens, competing claims and the identity of the seller. It did not make anyone a registrant. That happened in a second document, signed by a different party, under a different policy.

The Court Cleared the Liens. The Registry Made the Buyer.

    Zayo's IP Addresses Cannot Be Sold Without Zayo

    There is a comforting arithmetic in infrastructure finance: count the scarce things, price them against the last trade, add them to the pile. Registered IPv4 looks like it belongs in that pile. It is finite, it is held under a legal name, and the registry that assigns it publishes which organisation holds it. The comfort ends at the transfer rule, which is where the arithmetic has to stop and the operating question has to start.

    Who keeps the registry working after the rule writers leave?

    The organisations behind Internet addressing need rules for when things go wrong. The ASO Address Council has written a new proposal. Making it work would require more than a vote and a replacement nameplate.

    The Proof Arrives Too Early: Muhammad Usama Sardar’s Attested TLS Fight

    At RIPE 93, TU Dresden researcher Muhammad Usama Sardar explained how early attested TLS can deliver platform evidence without binding it tightly enough to the connection and hardware a client intends to trust. A question from the room exposed a second boundary: an IETF URL does not turn an individual draft into a standard.

Governance

A Route Server Can Count Your Prefixes. It Cannot Consent for You.

Breizh-IX can rebuild a strict filter every night. Its new RS-API proposal begins where tidy route lists stop: a customer's wish to have an announcement passed on is a separate instruction, and somebody has to keep that instruction attached to the running server.

NxtGen's sovereign cloud, beyond the supplier badge

Editorial position

Why BTW Media exists

  • Reality over advocacy
  • Evidence over sentiment
  • Systems over noise

Internet governance is too often described as theory, consensus, or institutional comfort while operators live with the consequences of structure, scarcity, jurisdiction, and incentives.

BTW shows how the system works when assumptions meet reality: clear, direct, evidence-led reporting that keeps the focus on structure rather than spectacle. We turn difficult infrastructure questions into analysis that operators, investors and policy leaders can use.

History of the Internet

Some Internet Clocks Were Two Years Late. Then Came the Count

In one 1988 Internet survey, a few computers answered the time question from a calendar two years away. David Mills did what any sensible person would do with a network full of confident clocks: he counted the answers, checked the denominators, and returned in 1989 with a much bigger experiment.

Conceptual 1989 Internet clock audit: disagreeing laboratory clocks, terminal hosts across a network map, a radio-referenced master clock and a worksheet of time measurements.
  1. The Link Was Shared. The Sales Pitch Was Bigger.
  2. The IPv4 Pool Was Free. The Future Title Office Was Up for Grabs.
  3. The Standards List Had an Expiry Date. The IAB Could Send a Protocol Back.

The Proxy Shrunk the Packet. The Tunnel MTU Did Not Grow.

One packet slips through because its repeated bytes have been folded away. The next packet is the same size before compression, but its bytes refuse to fold. A proxy that calls the first success a new tunnel MTU has sold a seat on a bridge that only one passenger can cross. MASQUE’s revised HTTP Datagram compression draft now draws the size boundary where the wire actually is: at the compressed frame, the current path and the receiver’s separate reconstruction limit.

A blue-striped packet is compressed as blue strips fall away; a thin packet crosses a narrow amber slot toward a larger receiving tray while a wider packet waits.
  1. The RPL Draft Wants Two Option Codes Already Taken
  2. Stripchat’s Corrected Estimate Fell Below 45 Million. Brussels’s 2023 DSA Call Still Stood.
  3. One List Survived. The 200 Mbps Path Stayed Valid.
