Background of Service Creation

During the dawn of the Internet in the 1980s and 90s, many IPv4 addresses were allocated free of charge to companies, universities, associations, foundations, and public institutions to facilitate the widespread adoption of the Internet.
At that time, it was uncertain how IPv4 addresses would be used, so their active utilization by large corporations and academic institutions was encouraged to promote the spread of the Internet.

However, at that time, it was not possible to transfer IPv4 addresses, and allocated addresses could only be used or returned.
However, after 2000, as the Internet rapidly proliferated, IPv4 addresses were held by mobile carriers, Internet service providers, server hosting companies, etc., and lending them to users (businesses and individuals) became the mainstream method for connecting to the Internet.

In this system, communication carriers lend IPv4 addresses to those who need them when they need them and reclaim them from those who no longer use them.
However, after 2011, due to the widespread adoption of smartphones and the ubiquity of Internet access, the IPv4 addresses allocated to communication carriers frequently became insufficient.

Consequently, in the same year, rules were established to liberalize the transfer of IPv4 addresses, allowing businesses to mutually lend and borrow IPv4 addresses.
Since our inception, our unwavering goal has been 'Internet for everyone'. We support the transfer of IPv4 addresses to aid in the development of the Internet and contribute to Japan's progress over the next century.

Glossary Explanation

IP Address (=Internet Protocol Address)

It is necessary to connect to the Internet. Having this allows connected devices to communicate with each other. Until the 2010s, IPv4 (IP version 4) addresses were the mainstream. Since 2020, the new standard of IPv6 (IP version 6) has become the mainstream.
Also, they can be broadly classified based on usage, into "Global IP Addresses" that can connect to the Internet worldwide, and "Private IP Addresses" used within company networks or home LANs. Among these, the Global IP Addresses are tradable.

IPv4 Address Exhaustion Issue

Now, including mobile phones, each person has more than one device connected to the Internet, leading to a physical shortage of IPv4 addresses. Therefore, measures to combat this exhaustion have been discussed since the inception of the Internet. One of these measures is the concept and technology of DHCP (Dynamic Host Configuration Protocol) and NAT (Network Address Translation).
These technologies have prevented exhaustion by recycling the limited number of IPv4 addresses. Now, we can use IPv6 addresses, a new standard of IP addresses (approximately 340 undecillion = 340 trillion x 100 trillion x 100 trillion), but devices and networks that still use IPv4 addresses exist, so their use continues.

PI Addresses & PA Addresses

PI addresses are IP addresses declared for use within an organization. PA addresses are IP addresses held by providers, and are declared to be further allocated to users.

Historical PI address

This is an abbreviation for 'Provider Independent Addresses,' which hold historical significance. Historical PI addresses refer to IPv4 addresses that were widely allocated to public institutions, academic institutions, and private companies when commercial Internet was expanding. This contributed to the spread of the Internet, but now there are many unused IPv4 addresses, which has led to issues like Internet latency.
