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

   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;

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.

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

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
