Supplemental data for "Lost in Space Improving Inference of IPv4 Address Space Utilization"
WHOIS map Introduction The power of the Internet springs from its ability to route information between machines all over the world. The Internet Protocol version 4 (IPv4) numerical address represents the smallest unit of this global routing infrastructure. The IPv4 routing system requires that each address be unique.
AS Core Visualizing IPv4 Topology at a Macroscopic Scale in 2017
IPv4 2013 Census Dataset. We infer utilization of the IPv4 address space and taxonomize /24 address blocks by analyzing and cross-correlating the following measurement datasets, all collected between July and October 2013: 4 types of passive traffic traces (from a darknet, an academic ISP, an IXP, and a residential ISP), 3 types of active measurements (ICMP ping, HTTP GET, traceroutes), BGP.
Which US city uses the most IPv4 public addresses? Network Monitoring Tools
We used these devices to build a distributed port scanner to scan all IPv4 addresses. These scans include service probes for the most common ports, ICMP ping, reverse DNS and SYN scans. We analyzed some of the data to get an estimation of the IP address usage.
The IPv4 Map
Figure 1: 2012 IPv4 Census Map, Hilbert Projection Figure 2: Browseable Hilbert map Figure 1 shows 420 Million IP addresses that responded to ICMP ping requests at least two times between June and October 2012. The IP space is mapped to a 2-dimensional Hilbert Curve as inspired by xkcd.

Overview One aspect of the MAPPING project is to estimate the fraction of used IPv4 addresses and the current usage patterns. The IPv4 Internet Map visualises the address usage. The map shows which parts of the Internet are more heavily used and which parts are more lightly used, or are not used at all.

We present an analysis comparing five demographic measures against three measures of Internet resources, stratified by continent with substratification by country.

The result was what the researcher called "the largest and most comprehensive IPv4 census ever." The animated map shows relative usage of IP addresses over a 24-hour period. IPv4 is the fourth.

January 14, 2022 An IP address is an unique address associated with a specific computer or network host. IP addresses are managed by the Internet Assigned Numbers Authority (IANA) and its regional registries to various organizations worldwide. IPv4 address uses a 32-bit address scheme.

Map of the The IPv4 Space of 2006
IPv4 addresses are collected into address blocks or subnets . All addresses in a subnet have the same initial bits (or prefix ). The subnet 128/8 includes almost 17 million addresses from 128.0.0.0 to 128.255.255.255, while the subnet 128.150/16 includes only 65,536 addresses of the form 128.150.x.y.

Static visualizations Visualizing Data
Our goal is to provide representatives that are responsive, complete and stable: that is, addresses that respond to pings and traceroutes (with high probability), that cover every allocated IPv4 /24 prefix, and that do not change much over time. Our hitlists are derived from our census data.
Study of IPv4 address allocation by continents
The census sets out to ping all IPv4 addresses allocated by the Internet Assigned Numbers Authority (IANA) with a fixed number of outstanding probes (1200) and a 5 second timeout resulting in a rate of approximately 250 probes per second [ 1 ].
