NAME

Net::Packet::IPv6 - Internet Protocol v6 layer 3 object

SYNOPSIS

use Net::Packet::Consts qw(:ipv6);
require Net::Packet::IPv6;

# Build a layer
my $layer = Net::Packet::IPv6->new(
   dst => $hostname6,
);
$layer->pack;

print 'RAW: '.unpack('H*', $layer->raw)."\n";

# Read a raw layer
my $layer = Net::Packet::IPv6->new(raw = $raw);

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

DESCRIPTION

This modules implements the encoding and decoding of the IPv6 layer.

RFC: ftp://ftp.rfc-editor.org/in-notes/rfc2460.txt

See also Net::Packet::Layer and Net::Packet::Layer3 for other attributes and methods.

ATTRIBUTES

version

Version of Internet Protocol header.

trafficClass

Traffic class field. Was Type of Service in IPv4.

flowLabel

Flow label class field. Was IP ID in IPv4.

nextHeader

The type of next header. Was protocol in IPv4.

protocol

Is an alias for nextHeader

payloadLength

Length in bytes of encapsulated layers (that is, layer 4 + layer 7).

hopLimit

Was TTL field in IPv4.

src

dst

Source and destination addresses.

METHODS

new

Object constructor. You can pass attributes that will overwrite default ones. Default values:

version: 6

trafficClass: 0

flowLabel: 0

nextHeader: NP_IPv6_PROTOCOL_TCP

hopLimit: 0xff

src: $Env->ip6

dst: '::1'

getPayloadLength

Returns the length in bytes of encapsulated layers (that is layer 4 + layer 7).

pack

Packs all attributes into a raw format, in order to inject to network. Returns 1 on success, undef otherwise.

unpack

Unpacks raw data from network and stores attributes into the object. Returns 1 on success, undef otherwise.

CONSTANTS

Load them: use Net::Packet::Consts qw(:ipv6);
