Version Tomorrow is the first day of the rest of your life

lecture: Internet-wide measurements: past, present and future [NEW: we'll scan during SHA live from Day 1]

Towards a holistic picture of the Internet's infrastructure and it's activity

Event large

This workshop will present past, present and possible future scanning strategies for the IPv4 address space (and beyond), BGP monitoring-, keeping track of AS/IP transitions, data correlation, error detection and globally distributed scanning. The participants will learn about different scanning methodologies (past & presently used), ongoing efforts by researchers, NGOs and RIRs. Next we'll introduce them to the concepts of running their own internet-wide scans and give them the possibility to try out their ideas on-site.

ATTENTION: The workshop doesn't require in-depth knowledge, but you should be familiar with Bash or Python scripting, Linux and TCP/IP basics.

SCANS DURING SHA2017: from day 1 until and after the workshop we will run IPv4-wide scans (among others) live on the internet via the SHA2017 uplink. You may participate on-site or remotely by submitting scans/ideas to `` - more details and collaboration via this document:

The presenter has been involved in internet-wide scanning for the past ~3 years and has co-authored several publications as a result of their scanning activity. But it's time to merge scanning efforts and take a step back to critically analyze our current scanning strategies, their longevity and reflect on the data - as well as ethical and privacy related questions - they yield.
