6. initial observations

• Key routers play huge role in global connectivity from a given source
• example, measured from Daniel's home:
  • 15 minutes
  • 13,900 destinations, mostly WWW servers
  • IP addresses spread across advertised IPv4 space
  • 22,756 intermediate IP addresses visited
  • number of routers touched is indeterminate
    (multiple IP addresses can map to same router)
  • only 165 IP addresses showed up in more than 1% of paths
