NAME

       Net::Frame::Layer::IPv6 - Internet Protocol v6 layer object

SYNOPSIS

          use Net::Frame::Layer::IPv6 qw(:consts);

          # Build a layer
          my $layer = Net::Frame::Layer::IPv6->new(
             version       => 6,
             trafficClass  => 0,
             flowLabel     => 0,
             nextHeader    => NF_IPv6_PROTOCOL_TCP,
             hopLimit      => 0xff,
             src           => '::1',
             dst           => '::1',
             payloadLength => 0,
          );
          $layer->pack;

          print 'RAW: '.$layer->dump."\n";

          # Read a raw layer
          my $layer = Net::Frame::Layer::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::Frame::Layer for other attributes and methods.

ATTRIBUTES

       version - 4 bits
           Version of Internet Protocol header.

       trafficClass - 8 bits
           Traffic class field. Was Type of Service in IPv4.

       flowLabel - 20 bits
           Flow label class field. Was IP ID in IPv4.

       nextHeader - 8 bits
           The type of next header. Was protocol in IPv4.

       protocol
           Is an alias for nextHeader.

       payloadLength - 16 bits
           Length in bytes of encapsulated layers (usually, that is layer 4 + layer 7).

       hopLimit - 8 bits
           Was TTL field in IPv4.

       src - 32 bits
       dst - 32 bits
           Source and destination addresses.

       The following are inherited attributes. See Net::Frame::Layer for more information.

       raw
       payload
       nextLayer

METHODS

       new
       new (hash)
           Object constructor. You can pass attributes that will overwrite default ones. See
           SYNOPSIS for default values.

       computeLengths ({ payloadLength => VALUE })
           In order to compute lengths attributes within IPv6 header, you need to pass via a
           hashref the number of bytes contained in IPv6 payload (that is, the sum of all layers
           after the IPv6 one).

       The following are inherited methods. Some of them may be overridden in this layer, and
       some others may not be meaningful in this layer. See Net::Frame::Layer for more
       information.

       layer
       computeLengths
       pack
       unpack
       encapsulate
       getLength
       print
       dump
