.US Harbors Prolific Malicious Link Shortening Service
by goemon＠sasami.anime.net 07 Nov '23

https://krebsonsecurity.com/2023/10/us-harbors-prolific-malicious-link-shor… "The NTIA recently published a proposal that would allow registrars to redact all registrant data from WHOIS registration records for .US domains. A broad array of industry groups have filed comments opposing the proposed changes, saying they threaten to remove the last vestiges of accountability for a top-level domain that is already overrun with cybercrime activity." What hope is there when registrars are actively aiding and abeting criminal enterprises? Are there any legitimate services running solely on .us domain names? -Dan

Survey for operators on IPv6 Extension Headers
by Justin Iurman 06 Nov '23

06 Nov '23

Hi NANOG, On behalf of the University of Liege (Belgium), we've been doing measurements on IPv6 Extension Headers over the last two years. More specifically, we're trying to evaluate how they are processed by routers along the path, and so from the edge. Now, we would like to compare our observations with the reality of operators. For that, we propose this very short survey [1] to operators and would really appreciate if you could complete it. Note that we guarantee anonymity of your answers by not sharing any data. Looking forward to your input. Thanks, Justin [1] https://docs.google.com/forms/d/e/1FAIpQLSeHgEWVQMrAbB9-pRf-T-mDHXxRxw-mAqO…
