The IPv4 Price Inversion

A curious price inversion has occurred in IPv4 markets. The long-term trend that discounted large blocks has reversed. The graph identifies /15 and /16 (large) block pricing per IP address throughout the period in the form of dark spots. It is evident that, for most of the timeframe here (2014 to the first half of 2021), large blocks sold at a significant discount. One might guess that the administrative chores related to large-network needs were most efficiently and cheaply satisfied with large blocks. more

Hijacked IP Addresses

From time to time, a party can get out of control. Raucous celebration can become careless, even destructive. Combine a critical number of young people, a certain amount of beer and lots of music and damage often happens. Partygoers leave a mess behind them. The same thing happens to some IP addresses. Malicious actors use IP addresses properly registered to someone else. more

IP Address Blocking

A network can fence its own IP addresses or block specific external ones from access. Administrators frequently block access to their own IP addresses to bar unwanted access to content. Individual IPs or blocks of IPs may also be blocked due to unwanted or malicious behavior. IP address blocking prevents a specific IP address or group of IP addresses from connecting with a server, computer, or application. more

IPv4 and Education: The Basics

An IP address is a unique identifier for a device on a network, including the internet. IP stands for Internet Protocol (IP) which is a set of rules (a protocol) for addressing and routing data so it can travel through networks and arrive at its intended destination. Hence, "address." Internet-connected devices such as computers and smartphones each have a unique IP address. more

Sanctions & The Regulation of IP Transfers

The early stages of internet development operated in a culture of independence from outside influence. In fact, as though to commemorate the spirit of the times, in 1996, John Perry Barlow wrote "A Declaration of the Independence of Cyberspace." In it, he told governments they "have no sovereignty where we gather." He went on to state, "Ours is a world that is both everywhere and nowhere, but it is not where bodies live." more
