by Carolyn Duffy Marsan, Network World As they imagine the Internet of 2020, computer scientists across the country are starting from scratch and re-thinking everything: from IP addresses to DNS to routing tables to Internet security in general.

net::dns::rr::spf5.18

Net::DNS::RR::SPF(3)					User Contributed Perl Documentation				      Net::DNS::RR::SPF(3)

NAME

       Net::DNS::RR::SPF - DNS SPF resource record

SYNOPSIS

	   use Net::DNS;
	   $rr = new Net::DNS::RR('name SPF spfdata ...');

	   $rr = new Net::DNS::RR( name    => 'name',
				   type    => 'SPF',
				   spfdata => 'single text string'
				   );

	   $rr = new Net::DNS::RR( name    => 'name',
				   type    => 'SPF',
				   spfdata => [ 'multiple', 'strings', ... ]
				   );

DESCRIPTION

       Class for DNS Sender Policy Framework (SPF) resource records.

       SPF records inherit most of the properties of the Net::DNS::RR::TXT class.

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.

   spfdata
	   $string = $rr->spfdata;
	   @list   = $rr->spfdata;

	   $rr->spfdata( @list );

       When invoked in scalar context, spfdata() returns the policy text as a single string, with text elements concatenated without intervening
       spaces.

       In a list context, spfdata() returns a list of the text elements.
