Net::DNS::RR::MX(3)

💖 NAME 💖

hey bestie!! welcome to the Net::DNS::RR::MX(3) page from the User Contributed Perl Documentation section — yep, manual name folded right in near the top like a little bow 🎀. This one is all about Net::DNS::RR::MX — DNS MX resource record, periodt.

---

🌸 SYNOPSIS 🌸

okay so you summon it like this, no cap:

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

---

🦋 DESCRIPTION 🦋

It’s the DNS Mail Exchanger (MX) resource record. That’s the whole description, and honestly? Short, iconic, done 💅.

---

💅 METHODS 💅

The available methods are those inherited from the base class augmented by the type-specific methods defined in this package. That’s the setup ✨.

Use of undocumented package features or direct access to internal data structures is discouraged and could result in program termination or other unpredictable behaviour. So like… don’t poke the internals, bestie 😭.

preference

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

A 16 bit integer which specifies the preference given to this RR among others at the same owner. Lower values are preferred — so lower is giving more main character energy here 👑.

exchange

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

A domain name which specifies a host willing to act as a mail exchange for the owner name. Slay, that’s the whole vibe 💌.
