NAME
Net::DNS::RR - DNS Resource Record class
SYNOPSIS
use Net::DNS::RR
DESCRIPTION
Net::DNS::RR is the base class for DNS Resource Record (RR) objects. See also the manual pages for each RR type.
METHODS
new
$rr = new Net::DNS::RR(
Name => "foo.bar.com",
TTL => 86400,
Class => "IN",
Type => "A",
Address => "10.1.2.3",
);
$rr = new Net::DNS::RR(
Name => "foo.bar.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.
$rrobj->print;Prints the record to the standard output. Calls the string method to get the RR's string representation.
string
print $rrobj->string, "\n";Returns a string representation of the RR. Calls the rdatastr method to get the RR-specific data.
rdatastr
$s = $rrobj->rdatastr;Returns a string containing RR-specific data. Subclasses will need to implement this method.
name
$name = $rrobj->name;Returns the record's domain name.
type
$type = $rrobj->type;Returns the record's type.
class
$class = $rrobj->class;Returns the record's class.
ttl
$ttl = $rrobj->ttl;Returns the record's time-to-live (TTL).
rdlength
$rdlength = $rrobj->rdlength;Returns the length of the record's data section.
rdata
$rdata = $rrobj->rdataReturns the record's data section as binary data.
BUGS
This version of Net::DNS::RR does no sanity checking on user-created RR objects.
