Net::DNS::RR::CAA(3)

💅 Net::DNS::RR::CAA — like, the DNS CAA record, bestie

okay so this is the Net::DNS::RR::CAA page from the perl manual, and honestly? it's giving "small but mighty" ✨ it's the class for Certification Authority Authorization (CAA) DNS resource records — yes, the ones that tell certificate authorities who's allowed to issue certs for your domain 👑

---

🌸 SYNOPSIS 🌸

like, the whole vibe in two lines:

use Net::DNS;
$rr = Net::DNS::RR->new('name IN CAA flags tag value');

that's it. that's the whole entrance. slay 💅

---

🦋 DESCRIPTION 🦋

Class for Certification Authority Authorization (CAA) DNS resource records. no cap, that's the whole description — she's concise, she's iconic, she doesn't overexplain 🎀

---

✨ METHODS ✨

The available methods are those inherited from the base class, plus the type-specific methods defined in this package. so you get the family inheritance AND the extra sparkle 🧚

⚠️ real talk: use of undocumented package features or direct access to internal data structures is discouraged and could result in program termination or other unpredictable behaviour. like, don't go poking around in her internals, bestie, it's not cute 😭

🎀 flags 🎀

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

Unsigned 8-bit number representing Boolean flags. eight whole bits of yes/no energy 🫶

💜 critical 💜

$rr->critical(1);

if ( $rr->critical ) {
        ...
}

That's the Issuer critical flag. she's the main character of the flags byte 👑

🌈 tag 🌈

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

Property identifier which may contain the characters a-z, A-Z, and 0-9. The tag field must not contain any other characters. Matching of tags is not case sensitive. periodt 💀 like, letters and digits only, no exceptions, and don't come at her with case-sensitivity drama.

🍓 value 🍓

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

A sequence of octets representing the property value. Property values are encoded as binary values and may employ sub-formats. so yeah, it's raw octets — she contains multitudes 💖
