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 2025: ASN Name Fixed-By 202585 2025-10-04 28685 ASN-ROUTIT 2025-10-30 Further information for the inferred remediation is available at: https://spoofer.caida.org/remedy.php Source Address Validation issues inferred during Oct 2025: ASN Name First-Spoofed Last-Spoofed 33915 TNF 2019-01-28 2025-10-28 39647 REDHOSTING 2019-12-02 2025-10-28 3920 IMS-RTFM 2023-10-06 2025-10-30 202585 2025-10-04 2025-10-04 42755 DATAFIBER 2025-10-08 2025-10-08 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
