We all know that IP addresses are poor long-term identifiers, because they’re not permanently assigned. But what if you want to accurately count the bots in a botnet and all you have is IP addresses? Thanks to @_LeonBock’s first @NDSSSymposium paper we have a solution! 🧵

Team-members from @caida_ioda, @OpenObservatory, @kentikinc, @CensoredPlanet, and political scientists from @UCSanDiego, analyzed diverse datasets to study #websiteblocking, #cellularshutdown, and #Internetconnectivityshutdown events in #Myanmar earlier this year.

“Monitoring and documenting internet shutdowns require complementary efforts. For instance, IODA focuses on monitoring regional or large-scale internet connectivity shutdowns while OONI is able to monitor social media and website blockings.” @rameses888
