All About IPv4 Blacklisting

Published on October 16th, 2019

The blacklisting of IP addresses is a common occurrence on today’s internet. Most of us have encountered networking attacks in one form or another, ranging from obnoxious spam emails to crippling malware, phishing or ransomware attacks. Their path to your computer starts from a device on the internet operating behind an IP address. Who helps...

IPv4 Price Trends and Insights

Published on March 29th, 2019

Figure 1. IPv4 prices have continued to rise in 2018. As shown in Figure 1, the price increases have been almost linear in nature from 2015 to the present. As of the beginning of March 2019, prices were at a minimum of $20 USD for block sizes of a /16 to a /21. To determine...

IPv4 Large Block Transfers

Published on March 22nd, 2018

In our February 2018 blog we looked at the large spike in IPv4 transfer volume in the 4th quarter of 2017. It became clear that the spike was mostly due to a high number of large block transfers. To dive into this deeper, we extracted data from the RIPE, ARIN and APNIC transfer logs to...

IPv4 Transfer Markets Soar in 4th Quarter 2017

Published on February 22nd, 2018

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,...

Global IPv4 Transfers Declining

Published on November 3rd, 2017

It has been a few months since we have commented on IPv4 transfer trends and we thought it would be interesting to determine, after transfers fell between 2015 and 2016, whether the reduction in transfers continued. So, we ran the numbers. Noting that the 2017 data is for 9 months, and not a full year,...

Transfers of IPv4 Addresses from /8s Held by One Organization

Published on May 10th, 2017

In 2011, as Nortel's Director of Engineering I started the orchestration of the sale of Nortel's 47.0.0.0/8. Over time this undertaking has resulted in the sale of approximately 85% of the /8. Something that has been discussed in the ensuing six years, is how many other “organization” or “company” owned /8s might ultimately be sold. IPv4...

IPv4 Transfer Volume and the Impact of the Inter-RIR IPv4 Transfer Market

Published on January 5th, 2017

As 2016 wound down, we thought we would take a look at the total volume of transfers and the number of IPv4 addresses that had been moved among ARIN, RIPE, and APNIC. Since December data was not yet available in all regions, the analysis was cut off at the end of November 2016. In doing...

IPv4 Addresses at NANOG

Published on February 3rd, 2016

IPv4 address bartering is a relatively new activity at NANOG meetings. I find it interesting to look back at the history of NANOG, to think about the purpose of its meetings, and then to examine the overlay of IPv4 meeting topics and IPv4 trading on that purpose. NANOG’s focus is on the Technologies and Systems...

The Future of IPv4

Published on January 18th, 2016

I would like to start by discussing IPv4 prices. My view is that the IPv4 price curve is shaped like a hill, as illustrated in Figure 1 above. Initially, there was a large IPv4 supply, which was a period of time best for the buyer, as prices were low. As time wore on, the number of available IPs...
