ASN stands for Autonomous System Number, which is a unique identifier assigned to an autonomous system (AS) that is responsible for routing internet traffic. In other words, an ASN is a way for internet service providers (ISPs) and network operators to identify and communicate with each other when exchanging internet traffic.
In Asia, there are several countries that own a significant number of ASNs, but the country with the most ASNs is China. As of October 2021, China has over 65,000 ASNs, followed by Japan with around 23,000 ASNs and India with around 18,000 ASNs.
China's dominance in the number of ASNs is not surprising given its large population and rapidly growing economy, which has led to a significant increase in internet usage and the need for more autonomous systems to manage internet traffic. The Chinese government has also been investing heavily in internet infrastructure, which has contributed to the growth of ASNs in the country.
Japan, on the other hand, has a well-established telecommunications industry and is known for its advanced technology, which has led to the development of many autonomous systems in the country. India, with its large and diverse population, has also seen a significant increase in internet usage in recent years, which has led to the growth of ASNs in the country.
Other countries in Asia with a significant number of ASNs include South Korea, Taiwan, Hong Kong, and Singapore. These countries have also seen significant growth in internet usage and have invested heavily in internet infrastructure, which has led to the development of many autonomous systems.
In conclusion, China currently owns the most ASNs in Asia, followed by Japan and India. ASN is an important identifier for internet service providers and network operators, and its growth in Asia reflects the increasing importance of the internet in the region's economy and society.
