Net::Packet::IPv6(3) User Contributed Perl Documentation Net::Packet::IPv6(3)

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

   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;

This modules implements the encoding and decoding of the IPv6 layer.

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
