How it's counted
The market figures come from the five registries' public transfer logs, read every day with the rest of the tracker.
What counts
- Market transfers: what the logs call a transfer (ARIN's NRPM 8.3 and 8.4, the other registries' transfer policies). Mergers and acquisitions (ARIN's 8.2 and the others' equivalents) are counted apart; AFRINIC's log has only those.
- IPv4 only. A transfer's size is all the addresses it moved, even when it moved several blocks.
- A transfer is dated by the registry's own log. In the charts, a transfer between two registries is dated by the log of the registry the addresses went to.
Transfers between two registries
They're in both registries' logs, often listed differently (one /22 in one log, four /24s in the other) and dated up to three weeks apart. Two records are taken as the same transfer when they move overlapping addresses in the same direction within 45 days of each other. In 2025, 1,127 of 1,136 such transfers were found in both logs; the other 9 are in one log only and counted from it.
Checked against ARIN's own figures
ARIN publishes yearly totals in /24s on its statistics page. Here they are next to this site's count, from ARIN's charts as read 2026-11-12 18:50 UTC. Two things make them differ: ARIN's figure for the current year runs to whenever ARIN last updated the chart, usually some weeks back; and some transfers are in the other registry's log but not in ARIN's public log (last column), which explains most larger differences. ARIN's charts sometimes count those anyway, so a match doesn't need that column to be empty.

Limits
- The logs say what moved and when, not the price or the reason. Sale prices aren't part of these pages.
- A transfer between two companies of the same group is in the logs like any other.
- Registries publish their logs with a delay of hours to days, so the latest days and the current month are incomplete.
