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 Oct 2020: ASN Name Fixed-By 6830 LGI-UPC 2020-10-15 39647 REDHOSTING 2020-10-21 Further information for the inferred remediation is available at: https://spoofer.caida.org/remedy.php Source Address Validation issues inferred during Oct 2020: ASN Name First-Spoofed Last-Spoofed 46562 TOTAL-SERVER-SOLUTIONS 2016-04-26 2020-10-08 8587 Infracom 2019-10-28 2020-10-30 213251 2020-07-30 2020-10-13 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
