DESCRIPTION:They say everything on the Internet is forever\, and while this
  may be true of your pictures from dinner last night\, the reality is that
  everything on the Internet is NOT forever. In fact\, much of the Internet
  is ephemeral\, or flappy\; services and hosts will appear online\, only t
 o disappear shortly after. This has major implications for research that u
 tilizes Internet scanning and begs the question – how often should we be
  scanning the Internet\, and how does this ephemerality differ across the 
 Internet?\n\nIn this talk\, I’ll discuss our findings from scanning the 
 Internet every hour for a week. I’ll share some interesting anecdotes ab
 out where uptime differed across three main variables: L4 ports\, L7 servi
 ces\, and ASNs. I’ll dive into examples where the portion of the Interne
 t was fairly stable (e.g. popular protocols on their standard ports) and w
 here uptime was\, well\, ephemeral (e.g. TCP SIP\, HTTP on non-standard po
 rts). I’ll discuss what these findings mean for the Internet Scanning co
 mmunity as a whole\, implications for scanning research\, and next steps. 
 My hope is that attendees leave understanding just how ephemeral the Inter
 net is\, and what they should do about it.
