IPv4 Scarcity Economics
Within the Topic facet, IPv4 Scarcity Economics topic intelligence connects articles that share a specific subject, signal focus, or monitoring theme. The page gives readers a richer path through related reporting, source evidence, market actors, and infrastructure implications, with enough context to understand why the topic matters across company movements, governance decisions, regional exposure, and operational risk. Readers can compare recurring signals, affected organisations, public evidence, market context, service continuity, procurement, competition, compliance, and strategic planning questions behind the subject instead of stopping at a thin list of matching articles. It explains what the topic covers, which infrastructure actors or policies are involved, what evidence supports the coverage, and why the subject may matter for operators, customers, investors, and policy readers.

Lee Howard Asked Whether an ISP Could Grade Its Own IPv4 Homework
At ARIN’s 2017 meeting, Lee Howard pictured a large ISP giving generous address blocks to its own departments, then presenting those assignments as proof that it needed more IPv4. The registry had an answer. The timing of the answer mattered.

An ISP Asked Cathy Aronson Which Stranger’s /8 It Should Borrow
The question sounded like a choice between 22.0.0.0/8 and 30.0.0.0/8. Cathy Aronson heard a more expensive question beneath it: what happens when a network builds its private life inside someone else’s public address space, then the owner comes home?

Rajesh Chharia Asked APNIC to Shrink IPv4 Slices Twice. It Agreed Once.
In 2008 a small network had to take too many addresses to get through the door. By 2023 the door had too few addresses left for everyone who might knock.

Gaurav Kansal’s IPv4 Plan Saw No Drawbacks. APNIC Found Four.
A proposal to give new networks twice as many IPv4 addresses came with a wonderfully short disadvantages section. The registry's assessment was less economical with its words.

Alain Durand Put IPv4 Aside for IPv6’s Awkward Teenage Years
In 2008, Durand proposed an odd-looking ration: save a piece of the scarce old Internet for builders of the new one. The rule still has a job, even though its individual grants no longer look like those in his first draft.

John Curran Put an IPv4 Jigsaw on ARIN’s Table
The waiting list can hold several small address blocks while one applicant waits for a single larger one. At ARIN 58, John Curran asked the community whether the pieces could be used together—and who should absorb the cost of doing so.

Cathy Aronson Was Asked Which Stranger’s /8 an ISP Could Borrow
The question arrived as if the Internet had a spare key under the mat. A large ISP wanted more internal IPv4 space and asked Cathy Aronson whether 22.0.0.0/8 or 30.0.0.0/8 was safer to use. She checked the premise before answering. The numbers already belonged to someone else's…

Vultr's $2.50 cloud has a rather small map
A global cloud footprint and a tiny virtual machine are different products. The useful price sits where computing, location and network access meet.

AFRINIC Has Four IPv4 Drawers. The Queue Is the Fifth.
A draft policy gives recovered addresses a holding pen, a history lesson and a destination. When two pools hit zero, the waiting list takes over—and every decision has to leave a ledger trail.

RIPE shut the extra-account door. The IPv4 queue added 20
Weeks after the registry restricted extra LIR accounts, its published IPv4 queue got longer. The two numbers belong on the same desk, even though different hands control them.

Tomohiro Fujisaki Put a Five-Year Timer on APNIC’s Last IPv4 Shelf
APNIC saved a little IPv4 for late arrivals. Fujisaki found the resale door and persuaded the room to put a clock on it.

Four blocks on the slide, one in your hand: ARIN's waitlist math
ARIN's own example puts four separate /24 blocks on the table. Its current rules let a qualifying applicant take one. The question is whether neat routing still deserves the last word on a scarce address queue.

ARIN’s legacy cleanup has 23 elephants in the address room
Most of ARIN’s remaining legacy IPv4 paperwork is attached to small blocks. Most of the addresses are elsewhere. A new registry slide deck puts 23 very large blocks at the centre of the job.
Story
ARIN has four IPv4 pieces. Its rule hands you one.
Four separate /24 blocks contain the addresses in a /22. ARIN says its waiting-list rules still forbid handing all four to one qualified applicant when they are not contiguous. The applicant can take a single /24 and leave the queue. At ARIN 58, staff finally put that little…

ARIN put the new holder’s one-year clock in the sender’s drawer
Receive one IPv4 block; try to transfer another later in the year; discover the whole organization is still inside ARIN’s waiting period. The manual hides the clock under sender rules, and ARIN says some new holders missed it. Staff has now put an uncomfortable second question on…

APNIC Links Three-Month Temporary IP Fees to Immediate Reassignment on Return
APNIC prices a temporary assignment by three-month periods, while its policy gives returned resources an unusually short route back into the assignment pool: once they are returned before the end date, they skip ordinary quarantine and are immediately available for another…

Thirty-nine IPv4 records, one bundle of addresses
ARIN and APNIC describe the same June movement in very different numbers of records. The difference is a useful warning for anyone trying to count the IPv4 market—or operate the addresses afterwards.

AFRINIC’s enforcement risk required protection for members
Court protection preserved members, allocated resources and AFRINIC itself. The six-month receivership deadline covered the whole board-reconstitution process.

Three Proposals for a Global IPv4 Policy: Paul Wilson’s Role in the First Attempt
Paul Wilson was one of nine people named on prop-069, the first of three attempts to define how IANA could redistribute IPv4 addresses returned after its free pool was exhausted. The proposal reached consensus in four regional processes, while a substantially revised fifth…

Milton L. Mueller Helped Make the IPv4 Address Market Measurable
A market can be real before anyone can count it well. Milton L. Mueller’s work on IPv4 transfers joined registry records, court filings and sampled routing data to make a disputed market visible. The method clarified what could be observed—and why a transfer count still could not…
