Below are detailed charts and statistics highlighting the IPv4 transfers in 2025. These figures are drawn from data reported by all Regional Internet Registries (RIRs) — ARIN, APNIC, RIPE, LACNIC and AFRINIC. The statistics focus on transfers of unused IP addresses and exclude those resulting from mergers and acquisitions. Additionally, this article includes historical data to offer a perspective on the variations in the market over the years.
Total number of IPv4 transfers in 2025
In 2025, there were 8062 IPv4 transfers, a decrease compared to the 8393 transfers in 2024.
Month-wise IPv4 transfers
The highest number of transfers occurred in December (1063), followed by January (1003) and March (940). The least activity was observed in May, with only 521 transfers.
Regions with the highest number of transfers
As the graph shows, RIPE had the highest number of unused blocks transferred (5068), followed by ARIN (2419) and APNIC (1166).
Inter-RIR transfers
ARIN had the highest number of inbound transfers (transfers from other RIRs) at 702, followed by RIPE (550) and APNIC (72)
LACNIC had the most outbound transfers (transfers to other RIRs) at 447, followed by ARIN (415) and APNIC (368)
Transfers by IP block size
In a shift from 2024, where /24 blocks were the most transferred, 2025 saw /24 blocks taking the lead, followed by /22 blocks.
Number of IPv4 transfers annually from 2017 to 2025
From 2017 to 2025, the highest number of transfers occurred in 2024, with a total of 8,393. This was followed by 8,333 transfers in 2021 and 8,062 in 2025. At the other end of the spectrum, 2017 recorded the lowest activity during this nine-year period, with just 4,565 IPv4 transfers.
Although 2017 recorded the fewest block transfers, it registered the second-highest volume of IPv4 addresses transferred, at 109.03 million. The peak year was 2018, with 111.51 million addresses transferred, followed by 2020 with 83.33 million and 2025 with 81.93 million. Notably, 2021 marked the lowest volume in the nine-year period, with only 52.04 million IPv4 addresses transferred.
This concludes our report on IPv4 transfers in 2025. The data in this report was compiled and analyzed by the Alpha Infolab team.
