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. It serves as location addressing, network interface identification and so on.
Data of IPv4 address allocations in 2021 is collected. The purpose of data collection is to observe and study the usage of IPv4 address allocations in 2021. With the data collected, a report titled ‘Internet IP Address 2022 Report‘ is generated. The percentage of IP Address Ownership by Country is recorded and displayed in table and charts form in this report. After that, an infographic is created and displayed below to give a better understanding of IPv4 address allocations in 2021. Data like a summary of IPv4 addresses allocated, IP address allocations by continents, usage types, organizations and so on are recorded and displayed in this infographic.
Based on the infographic as shown below, there is a total of 3.37 billion public IP addresses allocated in the year 2021. The United States is the country with the most public IP address as 37% of IP addresses are allocated to it. It is clearly shown that North America has the highest IP address allocation which is 40.5% although it had decreased by 0.52% if compared to the year 2020. The IP addresses allocated to Asia has the highest increment which is 1.29% even though its total IP address allocation (26.6%) is not the highest among others.
Furthermore, there is a total of 1.85 billion IP address allocation for ISP usage type, which is the highest among other usage types like DCH, COM and so on. Over the past 5 years, it had been observed that the IP changes based on the top 5 usage types fluctuate. A huge change is observed for MOB usage type. It had a slight increase in 2018-2019 and then a huge drop in 2019-2020 and increases back in 2020-2021. For DCH usage type, it drops significantly after the year 2018-2019.
Amazon Technologies which has 46 million IP addresses and Comcast Cable Communications which has 70 million IP addresses are the highest in group Data Center and ISP respectively. In addition, IP ownership in China has the highest increment, which is 6.18 million IP addresses added in 2021 whereas IP ownership in the United States has the highest decrement, which is 8.74 million IP addresses reduced if compared to the year 2020.
Overall, the United States which is located in North America is assigned most of the IP addresses in 2021. The infographic below is for your reference to manage or make use of IP addresses in the future.
