In response to feedback from operational security communities,
CAIDA's source address validation measurement project
(https://spoofer.caida.org) is automatically generating monthly
reports of ASes originating prefixes in BGP for systems from which
we received packets with a spoofed source address.
We are publishing these reports to network and security operations
lists in order to ensure this information reaches operational
contacts in these ASes.
This report summarises tests conducted within nld.

Amsterdam.
We have just opened the ticketstore, and everybody can sign up.
As always, attendance is free for everyone thanks to the help of all
of our amazing sponsors - but we're offering the possibility to
help out in sponsoring us by offering paid tickets as well.
All tickets are available via https://nlnog.net/tickets .
The programme for this NLNOG day is not yet complete, but we will
make it into an exciting day, filled with lots of presentations on
interesting topics.
The event is typically sold out, so be quick in reserving your spot!
