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. Inferred improvements during Feb 2020: none inferred Source Address Validation issues inferred during Feb 2020: ASN Name First-Spoofed Last-Spoofed 9009 M247 2017-01-10 2020-02-29 28685 ASN-ROUTIT 2017-03-26 2020-02-27 6830 LGI-UPC 2017-06-14 2020-02-29 8587 Infracom 2019-10-28 2020-02-26 209299 2019-12-15 2020-02-20 Further information for these tests where we received spoofed packets is available at: https://spoofer.caida.org/recent_tests.php?country_include=nld&no_block=1 Please send any feedback or suggestions to spoofer-info@caida.org
