NAME
    Net::DNS::RR::SOA - DNS SOA resource record

SYNOPSIS
        use Net::DNS;
        $rr = Net::DNS::RR->new('name SOA mname rname 0 14400 3600 1814400 3600');

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;
        $rr->mname( $mname );

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

  rname
        $rname = $rr->rname;
        $rr->rname( $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;
        $rr->refresh( $refresh );

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

  retry
        $retry = $rr->retry;
        $rr->retry( $retry );

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

  expire
        $expire = $rr->expire;
        $rr->expire( $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;
        $rr->minimum( $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 auxilliary SEQUENTIAL() function can never satisfy the
    serial number ordering constraint.

  Date Encoded
        $successor = $soa->serial( YYYYMMDDxx );

    The 32 bit value returned by the auxilliary 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 auxilliary UNIXTIME() function will
    used if it satisfies the ordering constraint, otherwise the existing
    serial number will be incremented as above.
