1, The Full Form of ASN is American Society of Nephrology

Founded in 1966, the American Society of Nephrology (ASN) is the world’s largest professional society devoted to the study of kidney disease. Composed of over 20,000 physicians and scientists, ASN promotes expert patient care, advances medical research, and educates the renal community. ASN also informs policymakers about issues of importance to kidney doctors and their patients.

To create a world without kidney diseases, the ASN Alliance for Kidney Health elevates care by educating and informing, driving breakthroughs and innovation, and advocating for policies that create transformative changes in kidney medicine throughout the world.

2, The Full Form of ASN is Advance Shipping Notice.

An advance ship notice or advance shipping notice (ASN) is a notification of pending deliveries, similar to a packing list. It is usually sent in an electronic format and is a common EDI document. In the EDI X12 system, it is known as the EDI 856 document and the EDIFACT equivalent is the DESADV (Dispatch Advice) message. The ASN can be used to list the contents of a shipment of goods as well as additional information relating to the shipment, such as order information, product description, physical characteristics, type of packaging, markings, carrier information, and configuration of goods within the transportation equipment. The ASN enables the sender to describe the contents and configuration of a shipment in various levels of detail and provides an ordered flexibility to convey information.

3, The Full Form of ASN is Autonomous System Number

An Autonomous System (AS) is a group of one or more IP prefixes (lists of IP addresses accessible on a network) run by one or more network operators that maintain a single, clearly-defined routing policy. Network operators need Autonomous System Numbers (ASNs) to control routing within their networks and to exchange routing information with other Internet Service Providers (ISPs).

Each AS is assigned an autonomous system number (ASN), for use in Border Gateway Protocol (BGP) routing. Autonomous System Numbers are assigned to Local Internet Registries (LIRs) and end user organizations by their respective Regional Internet Registries (RIRs), which in turn receive blocks of ASNs for reassignment from the Internet Assigned Numbers Authority (IANA). The IANA also maintains a registry of ASNs which are reserved for private use (and should therefore not be announced to the global Internet).

There are two different formats to represent ASNs: 2-byte and 4-byte.

A 2-byte ASN is a 16-bit number. This format provides for 65,536 ASNs (0 to 65535). From these ASNs, the Internet Assigned Numbers Authority (IANA) reserved 1,023 of them (64512 to 65534) for private use.

A 4-byte ASN is a 32-bit number. This format provides for 2³² or 4,294,967,296 ASNs (0 to 4294967295). IANA reserved a block of 94,967,295 ASNs (4200000000 to 4294967294) for private use.

Up until the Internet Engineering Task Force (IETF) proposed a gradual transition to 4-byte ASNs in 2007, all ASNs were 2-byte. There is no longer a distinction between a 2-byte and 4-byte ASN, and all ASNs should be considered 4-byte.
