NAME¶
Net::DNS::RR::SVCB - DNS SVCB resource record
SYNOPSIS¶
use Net::DNS;
$rr = Net::DNS::RR->new('name HTTPS SvcPriority TargetName alpn=h3,...');
DESCRIPTION¶
DNS Service Binding (SVCB) resource record
Service binding and parameter specification via the DNS (SVCB and HTTPS RRs)
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.
SvcPriority¶
$svcpriority = $rr->svcpriority;
$rr->svcpriority( $svcpriority );
The priority of this record (relative to others, with lower values preferred). A value of 0 indicates AliasMode.
TargetName¶
$rr->targetname( $targetname );
$effecivetarget = $rr->targetname;
The domain name of either the alias target (for AliasMode) or the alternative endpoint (for ServiceMode).
For AliasMode SVCB RRs, a TargetName of "." indicates that the service is not available or does not exist.
For ServiceMode SVCB RRs, a TargetName of "." indicates that the owner name of this record must be used as the effective TargetName.
mandatory, alpn, no-default-alpn, port, ipv4hint, echconfig, ipv6hint¶
$rr = Net::DNS::RR->new( 'svc.example. SVCB 1 svc.example. port=1234' );
$rr->port(1234);
$string = $rr->port(); # \004\210
$rr->key3($string);
Constructor methods for mnemonic SvcParams defined in draft-ietf-dnsop-svcb-https-01. When invoked without arguments, the methods return the presentation format value for the underlying key. The behaviour with undefined arguments is not specified.
keyNN¶
$keynn = $rr->keyNN;
$rr->keyNN( $keynn );
Generic constructor and accessor methods for SvcParams. The key index NN is a decimal integer in the range 0 .. 65534. The method argument and returned value are both presentation format strings. The method returns the undefined value if the key is not present. A (key,value) pair will be ignored if the value is undefined.
