NAME
       Net::DNS::RR::SOA - DNS SOA resource record
SYNOPSIS
           use Net::DNS;
           $rr = new Net::DNS::RR('name SOA mname rname 0 86400 3600 604800 10800');
DESCRIPTION
       Class for DNS Start of Authority (SOA) resource records.
METHODS
       The available methods are those inherited from the base class augmented
       by the type-specific methods defined in this package.
       Use of undocumented package features or direct access to internal data
       structures is discouraged and could result in program termination or
       other unpredictable behaviour.
   mname
           $mname = $rr->mname;
       The domain name of the name server that was the original or primary
       source of data for this zone.
   rname
           $rname = $rr->rname;
       The mailbox which identifies the person responsible for maintaining
       this zone.
   serial
           $serial = $rr->serial;
           $serial = $rr->serial(value);
       Unsigned 32 bit version number of the original copy of the zone.  Zone
       transfers preserve this value.
       RFC1982 defines a strict (irreflexive) partial ordering for zone serial
       numbers. The serial number will be incremented unless the replacement
       value argument satisfies the ordering constraint.
   refresh
           $refresh = $rr->refresh;
       A 32 bit time interval before the zone should be refreshed.
   retry
           $retry = $rr->retry;
       A 32 bit time interval that should elapse before a failed refresh
       should be retried.
   expire
           $expire = $rr->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
           $minimum = $rr->minimum;
       The unsigned 32 bit minimum TTL field that should be exported with any
       RR from this zone.
Zone Serial Number Management
       The internal logic of the serial() method offers support for several
       widely used zone serial numbering policies.
   Strictly Sequential
           $successor = $soa->serial( SEQUENTIAL );
       The existing serial number is incremented modulo 2**32 because the
       value returned by the auxiliary SEQUENTIAL() function can never satisfy
       the serial number ordering constraint.
   Date Encoded
           $successor = $soa->serial( YYYYMMDDxx );
       The 32 bit value returned by the auxiliary YYYYMMDDxx() function will
       be used if it satisfies the ordering constraint, otherwise the serial
       number will be incremented as above.
       Serial number increments must be limited to 100 per day for the date
       information to remain useful.
   Time Encoded
           $successor = $soa->serial( UNIXTIME );
       The 32 bit value returned by the auxiliary UNIXTIME() function will
       used if it satisfies the ordering constraint, otherwise the existing
       serial number will be incremented as above.
