Net::DNS::RR::KX(3)

💌 Net::DNS::RR::KX — DNS KX resource record

okay so bestie, welcome to the manual page for Net::DNS::RR::KX(3) — a User Contributed Perl Documentation page, no cap. It's the DNS KX resource record, and it's honestly kind of iconic once you get what it's doing. Let's get into it ✨

---

🌸 NAME

Net::DNS::RR::KX — the DNS KX resource record. that's it, that's the name, short and slay 💅

---

🎀 SYNOPSIS

the whole vibe, in code:

use Net::DNS;
$rr = Net::DNS::RR->new('name KX preference exchange');

yes bestie, one line and you've summoned a whole KX record out of the void 🦋

---

✨ DESCRIPTION

it's a DNS Key Exchange Delegation (KX) record. literally what it says on the tin. key exchange delegation. delegation of key exchange. the record that says "hey, this other host over here is willing to do key exchange for me" 🔥

---

💖 METHODS

so here's the tea: the methods you get are those inherited from the base class, plus the type-specific methods this package defines itself. inherited + augmented, the classic glow-up 🌈

ngl, use of undocumented package features or direct access to internal data structures is discouraged — and it could result in program termination or other unpredictable behaviour. so like. don't go poking around in there, bestie 😭 🙈

---

🌟 preference

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

it's a 16 bit integer which specifies the preference given to this RR among others at the same owner. lower values are preferred — so like, smaller number = higher priority, which is giving "pick me, I'm the low-maintenance one" energy 👑

get it with $rr->preference, set it with $rr->preference( $preference ). slay 🫶

---

🦋 exchange

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

a domain name which specifies a host willing to act as a key exchange for the owner name. like, "here's the host that'll handle it for me" ✨

get it with $rr->exchange, set it with $rr->exchange( $exchange ). periodt 💜
