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.

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.
