 where:

 ADDRESS         An 32 bit Internet address

 PROTOCOL        An 8 bit IP protocol number

 <BIT MAP>       A variable length bit map.  The bit map must be a
                 multiple of 8 bits long.

Method Detail

newInstance

public static DnsRDataWks newInstance(byte[] rawData,
                                      int offset,
