This attribute identifies the NAS that constructed the Access-Request packet. Most often, the fully qualified domain name (FQDN) is used in the value portion of this attribute (for instance, local-nas3.raleigh.corp.hasselltech.net), although the RFC states that the value must be treated as a series of undistinguished octets. The FQDN is often used to eliminate duplicate NAS identifiers and reduce confusion for the client.

This attribute is often vendor specific and each implementation may have customized the use and behavior of this attribute. Additionally, in transactions involving a proxy server, this value can become mangled.

QuotationMarkI wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
