NAME

Net::DNS::RR - DNS Resource Record class
 

SYNOPSIS

DESCRIPTION

METHODS

new (from string)

 $a     = Net::DNS::RR->new("foo.example.com. 86400 A 10.1.2.3");
 $mx    = Net::DNS::RR->new("example.com. 7200 MX 10 mailhost.example.com.");
 $cname = Net::DNS::RR->new("www.example.com 300 IN CNAME www1.example.com");
 $txt   = Net::DNS::RR->new("baz.example.com 3600 HS TXT 'text record'");

Returns a "Net::DNS::RR" object of the appropriate type and initialized from the string passed by the user. The format of the string is that used in zone files, and is compatible with the string returned by "Net::DNS::RR->string".

The name and RR type are required; all other information is optional. If omitted, the TTL defaults to 0 and the RR class defaults to IN. Omitting the optional fields is useful for creating the empty RDATA sections required for certain dynamic update operations. See the "Net::DNS::Update" manual page for additional examples.

All names must be fully qualified. The trailing dot (.) is optional.  

new (from hash)

 $rr = Net::DNS::RR->new(
         name    => "foo.example.com",
         ttl     => 86400,
         class   => "IN",
         type    => "A",
         address => "10.1.2.3",
 );

 $rr = Net::DNS::RR->new(
         name => "foo.example.com",
         type => "A",
 );

Returns an RR object of the appropriate type, or a "Net::DNS::RR" object if the type isn't implemented. See the manual pages for each RR type to see what fields the type requires.

The "Name" and "Type" fields are required; all others are optional. If omitted, "TTL" defaults to 0 and "Class" defaults to IN. Omitting the optional fields is useful for creating the empty RDATA sections required for certain dynamic update operations.

The fields are case-insensitive, but starting each with uppercase is recommended.  

print

    $rr->print;

Prints the record to the standard output. Calls the string method to get the RR's string representation.  

string

    print $rr->string, "\n";

Returns a string representation of the RR. Calls the rdatastr method to get the RR-specific data.  

rdatastr

    $s = $rr->rdatastr;

Returns a string containing RR-specific data. Subclasses will need to implement this method.  

name

    $name = $rr->name;

Returns the record's domain name.  

type

    $type = $rr->type;

Returns the record's type.  

class

    $class = $rr->class;

Returns the record's class.  

ttl

    $ttl = $rr->ttl;

Returns the record's time-to-live (TTL).  

rdlength

    $rdlength = $rr->rdlength;

Returns the length of the record's data section.  

rdata

    $rdata = $rr->rdata

Returns the record's data section as binary data.
