This value carries the IP address of
the host that provides the login service for a specific connection.
Most commonly this IP address is the address of the actual host, but
there are two reserved values that specialize the RADIUS
client’s behavior. If a value of
255.255.255.255
(0xFFFFFFFF
) is
placed in this attribute, then the client needs to assign this host
IP itself. If a value of 0.0.0.0
(0x00000000
) is placed in this attribute, then the
client user should determine and configure this IP address for his
connection.
Multiple instances of this packet may be present. The RFC doesn’t specify what behavior the RADIUS client should present when it encounters this, but an educated guess would be to allow a selection of host IP addresses for redundancy, fault tolerance, and load balancing.
