26 *
27 * A result class number is an unsigned 16 bit number.  Each class may
28 * contain up to 65536 results.  A result code is formed by adding the
29 * result number within the class to the class number multiplied by 65536.
30 *
31 * Classes < 1024 are reserved for ISC use.
32 * Result classes >= 1024 and <= 65535 are reserved for application use.
