Pool of Viable IPv4 Addresses Smaller Than It Appears

Pool of Viable IPv4 Addresses Smaller Than It Appears(Ping! Zine Web Tech Magazine) – On September 3, APNIC Scientist and Kalorama blog guest contributor, Geoff Huston, published a post explaining how and why some IPv4 addresses are more viable – and therefore valuable – than others. His piece, “All IP Addresses Are Not The Same“, includes the results and analysis of several tests that Huston ran on IPv4 addresses and points out that even supposedly unused or ‘free’ IPv4 addresses can receive high levels of traffic.

“Certain IP addresses receive a higher volume of data traffic than others, either because of common scanning, UDP streaming during P2P connection, DNS zone errors, or vendor equipment flaws,” explained Huasong “Joe” Zhou of the Kalorama Group. “This is important for businesses to understand, especially datacenters, telecoms and carriers, because IPv4 addresses with low rates of historical traffic are less likely to be flagged for spam or phishing.”

Zhou, who is currently based in China, went on to explain that the demand for clean IPv4 addresses will only increase as the world waits for the majority of networks to switch to IPv6. He recommends that companies simultaneously begin preparing for IPv6 migration as they assess whether their current IPv4 levels are sufficient.
