NAME

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

SYNOPSIS

   use Net::Packet::IPv6;

   # Build layer to inject to network
   my $ip6 = Net::Packet::IPv6->new(
      dst => $hostname6,
   );

   # Decode from network to create the object
   # Usually, you do not use this, it is used by Net::Packet::Frame
   my $ip6Decoded = Net::Packet::IPv6->new(raw = $rawFromNetwork);

   print $ip6->print, "\n";

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.

flowLabel

Flow label class field. Was IP ID in IPv4.

nextHeader

The type of next header. Was protocol in IPv4.

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);

NP_IPv6_PROTOCOL_TCP
NP_IPv6_PROTOCOL_UDP

Constants for nextHeader attribute.
