WebThe AS is assigned a globally unique 16 digit identification number一known as the autonomous system number or ASN一by the Internet Assigned Numbers Authority (IANA). Autonomous systems numbered one to 64511 are available by IANA for global use. The 64512 to 65535 series is reserved for private and reserved purposes. WebUntil 2007, all autonomous system numbers were 16 bits or 2 bytes, which resulted in 65,536 possible ASNs for allocation. But just like the IPv4 range, that amount of ASNs was always destined to run out. Therefore, they created new 4-byte (32-bit) ASNs to solve that issue, which resulted in 4,294,967,296 possible ASNs to distribute. WebAn Autonomous System (AS) is a group of one or more IP prefixes run by one or more network operators that maintains a single, clearly defined routing policy. An IP prefix is a list of IP addresses that can be reached from that ISP’s network. shanghai maxim garment accessories co ltd
