public class AlternateServerAttribute
extends AddressAttribute

The ALTERNATE-SERVER attribute indicates the IP address and port of an alternate server the client could use. For example, alternate servers may contains special capabilities. It consists of an eight bit address family, and a sixteen bit port, followed by a fixed length value representing the IP address. 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |x x x x x x x x| Family | Port | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Address | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ The port is a network byte ordered representation of the mapped port. The address family is always 0x01, corresponding to IPv4. The first 8 bits of the ALTERNATE-SERVER are ignored, for the purposes of aligning parameters on natural boundaries. The IPv4 address is 32 bits.
