NAME

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

CONTENTS

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 <B>Net::Packet::LayerB> and <B>Net::Packet::Layer3B> for other attributes and methods.

ATTRIBUTES

<B>versionB> Version of Internet Protocol header.
<B>trafficClassB> Traffic class field. Was Type of Service in IPv4.
<B>flowLabelB> Flow label class field. Was IP ID in IPv4.
<B>nextHeaderB> The type of next header. Was protocol in IPv4.
<B>protocolB> Is an alias for <B>nextHeaderB>
<B>payloadLengthB> Length in bytes of encapsulated layers (that is, layer 4 + layer 7).
<B>hopLimitB> Was TTL field in IPv4.
<B>srcB>
<B>dstB> Source and destination addresses.

METHODS

<B>newB> 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’

<B>getPayloadLengthB> Returns the length in bytes of encapsulated layers (that is layer 4 + layer 7).
<B>packB> Packs all attributes into a raw format, in order to inject to network. Returns 1 on success, undef otherwise.
<B>unpackB> 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);
<B>NP_IPv6_PROTOCOL_TCPB>
<B>NP_IPv6_PROTOCOL_UDPB> Constants for <B>nextHeaderB> attribute.
