Subject: [NLNOG] Spoofer Report for NLNOG for Oct 2025
Message-ID: <1762624808.987072.10019.nullmailer@caida.org>

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
