The IPv4 transfer market experienced a huge spike in the last quarter of 2017. By the end of September (Q1 to Q3) a total of 23.0 million IPs had been transferred. The final number of IPs transferred in 2017 equaled 65.5 million, which means there were 42.5 million IPs transferred in the fourth quarter alone, which is more than the first three quarters combined and more than all of 2016.
It was interesting to breakdown where this volume came from. We compared the number of transfers to the number of IPs transferred:
While there was a reasonable increase in the number of transfers in ARIN region, it has certainly not doubled. Yet, the number of IPs transferred more than doubled. In RIPE this pattern is magnified with a steady number transfers from 2016 to 2017, yet almost 3x the number of IPs transferred. Hence it is clear that the increase is due to a skewing of the size of the transfers from small blocks to larger blocks.
This becomes clear when we look at the very large transfers:
The above points help to show where the sudden increased volume came from. This raises the question: Can the increased transfer volume continue in 2018? More to come, in our next blog.
