IPv4 transfer statistics
What the public transfer record actually shows about how the IPv4 market has moved.
Every IPv4 transfer recorded by RIPE NCC, ARIN and APNIC is public. DCXV tracks over 112,000 of them, and the tables below are counted directly from that record rather than estimated.
Counts are of transfer records, not of addresses: one record can move a single /24 or a large contiguous block, so a year with fewer records did not necessarily move fewer addresses.

- A transfer record is one registry event, covering one or more address blocks.
- The registry shown is the source registry, which is where the space was held before the transfer.
- Block size is the prefix length of the transferred range, so a smaller number means a larger block.
- The current year is incomplete and will keep rising until it ends.

Questions and answers
- Where does this data come from?
The public transfer records published by RIPE NCC, ARIN and APNIC. DCXV tracks over 112,000 of them and counts these figures directly from that record.
- How far back does it go?
To 2009, which is the earliest year with recorded transfers. Volume was negligible until about 2014 and has run in the thousands per year since.
- Does a transfer record equal one block?
No. One record can cover several address ranges, so record counts and address volumes are different measures.
- Can I see the underlying transfers?
Yes. The transfer database is browsable, and each registry and block-size row here links to its own filtered listing.
