An Autonomous System Number (ASN) is a unique identifier that is assigned to an organization that operates its own network and has control over the routing of its IP addresses. It is used to identify the network on the internet and is an important aspect of internet routing.
CIDR notation, as explained earlier, is a method of allocating IP addresses that allows for efficient use of address space.
An Autonomous System Number (ASN) is a unique identifier assigned to an organization that has control over a specific block of IP addresses. An ASN is used to identify and route internet traffic to the organization's network. The ASN 2510 is assigned to Fujitsu Limited, which is an Australian telecommunications company. This ASN is used to identify the network owned and operated by Fujitsu Limited.
When a device sends or receives data over the internet, it must first identify the network it belongs to using its IP address. The data is then routed through various networks until it reaches its destination. Routing is facilitated by routers, which use routing tables to determine the best path for the data to take. The routing tables contain information about the IP addresses and ASNs of the various networks that make up the internet.
In conclusion, CIDR notation and ASN are essential concepts in the management and allocation of IP addresses on the internet. CIDR notation allows for efficient use of address space, while ASN is used to identify and route internet traffic to the organization's network. Understanding these concepts is crucial for network administrators to manage and allocate IP addresses efficiently and ensure the smooth functioning of the internet.
