Page 18: ID Field Encoding

Page 18

  
  ID Field Encoding
  Each IP packet has an ID to allow packet defragmentation.
  Two bytes long
  Normally increments each time.
  Encode our data in the ID field
  Cannot correctly identify order - must send packets slowly
  Can't be part of a legit connection
  Sender must create raw IP packets
  Receiver must sniff IP packets
  One to two bytes per packet
  Works best on simple packet filters.
