💖 Net::F...ragment(3pm) 💖

okay bestie, so this is the manual page for Net::Frame::Layer::IPv6::Fragment, which lives in the User Contributed Perl Documentation corner of the universe ✨. It's giving Internet Protocol v6 Fragment Extension Header layer object energy, and honestly? she's iconic. Let's get into it 🫶

✨ NAME ✨

Net::Frame::Layer::IPv6::Fragment — the Internet Protocol v6 Fragment Extension Header layer object 💅 no cap, that's literally the whole name.

---

🌈 SYNOPSIS 🌈

here's how you actually use her, copy-paste friendly and everything:

use Net::Frame::Simple;
use Net::Frame::Layer::IPv6::Fragment;

my $icmp = Net::Frame::Layer::IPv6::Fragment->new(
   nextHeader     => NF_IPv6_PROTOCOL_TCP,
   reserved       => 0,
   fragmentOffset => 0,
   res            => 0,
   mFlag          => 0,
   identification => 0
);

#
# Read a raw layer
#

my $layer = Net::Frame::Layer::IPv6::Fragment->new(raw => $raw);

print $layer->print."\n";
print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n"
   if $layer->payload;

periodt. that's the whole vibe check right there 💖

🦋 DESCRIPTION 🦋

so basically this module implements the encoding and decoding of the IPv6 Fragment Extension Header layer. that's the tea ☕

RFC, for the girlies who like receipts: ftp://ftp.rfc-editor.org/in-notes/rfc2460.txt

also, go peek at Net::Frame::Layer for other attributes and methods, she's the main character of the family 👑

🎀 ATTRIBUTES 🎀

here's every single one, no skipping, we don't do that here:

• nextHeader — the protocol number of the next header that comes after the Fragment header. it's the "who's next" of the situation ✨
• reserved — not used at all bestie; set it to zeroes. it's just sitting there, minding her business 💀
• fragmentOffset — specifies the offset, or position, in the overall message where the data in this fragment goes. it's measured in units of 8 bytes (that's 64 bits for the math girlies) and it gets used in a way that's very similar to the field of the same name in the IPv4 header. twins fr fr 👯
• res — not used; set to zeroes. yeah she's basically the same energy as reserved, lowkey redundant, highkey fine 🌸
• mFlag — same as the flag of the same name in the IPv4 header. when it's set to 0, it indicates this is the last fragment in a message 🎬; when it's set to 1, it indicates that more fragments are yet to come in the fragmented message 😭 the suspense!!
• identification — same as the field of the same name in the IPv4 header, except she got expanded to 32 bits 💅 she contains a specific value that's common to each of the fragments belonging to a particular message, so that pieces from different fragmented messages don't get mixed together. she's the group chat admin keeping everyone in the right thread, periodt 🧚

the following are inherited attributes — see Net::Frame::Layer for more info:

• raw
• payload

💜 METHODS 💜

new

new (hash)

Object constructor ✨ you can pass attributes in and they'll overwrite the default ones. see SYNOPSIS for the default values, they're all listed up there, go look, i'll wait 🫶

the following are inherited methods. some of them may be overridden in this layer, and some others may not be meaningful in this layer at all — no cap, that's just how it is. see Net::Frame::Layer for more information:

• layer
• computeLengths
• computeChecksums
• pack
• unpack
• encapsulate
• getLength
• getPayloadLength
• print
• dump
