 where:

 MNAME           The <domain-name> of the name server that was the
                 original or primary source of data for this zone.

 RNAME           A <domain-name> which specifies the mailbox of the
                 person responsible for this zone.

 SERIAL          The unsigned 32 bit version number of the original copy
                 of the zone.  Zone transfers preserve this value.  This
                 value wraps and should be compared using sequence space
                 arithmetic.

 REFRESH         A 32 bit time interval before the zone should be
                 refreshed.

 RETRY           A 32 bit time interval that should elapse before a
                 failed refresh should be retried.

 EXPIRE          A 32 bit time value that specifies the upper limit on
                 the time interval that can elapse before the zone is no
                 longer authoritative.

 MINIMUM         The unsigned 32 bit minimum TTL field that should be
                 exported with any RR from this zone.

Method Detail

newInstance

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