Net::DNS::Packet.parse

Create a new instance of Net::DNS::Packet class from binary data, taken
out by a network stream. For example:

  # udp_socket is an UDPSocket waiting for a response
  ans = udp_socket.recvfrom(1500)
  packet = Net::DNS::Packet::parse(ans)

An optional +from+ argument can be used to specify the information
of the sender. If data is passed as is from a Socket#recvfrom call,
the method will accept it.

Be sure that your network data is clean from any UDP/TCP header, 
expecially when using RAW sockets.
