Out of curiosity, since we aren't affected by this ourselves, I know of cases where Cogent has sub-allocated IP space to its customers but which those customers originate from their own ASN and then announce to multiple upstream providers. So while the IP space is registered to Cogent and allocated to its customer, the AS-path might be something like ^174_456$ but it's entirely possible that ARIN would observe it as ^123_456$ instead. Are such IP address blocks affected by the suspension? Best regards, Martijn On 1/7/20 5:30 AM, John Curran wrote: ARIN has suspended service for all Cogent-registered IP address blocks. Customers with their own IP blocks blocks that are simply being announced by Cogent are not affected. /John John Curran President and CEO American Registry for Internet Numbers On Jan 6, 2020, at 9:44 PM, Ross Tajvar <ross@tajvar.io><mailto:ross@tajvar.io> wrote: Yeah this raises a great point - I'm curious how ARIN is differentiating between cogent and cogens customers when monitoring for prohibited access. Particularly those customers whose IPs belong to and are announced by Cogent.

Can you define exactly what services have been blocked? IRR/ROA/TLA registry updates, etc? Were they blocked ^174 or 174$? This is a precedent AFAIK. I’d like to understand consequences.

I just had (yet another) Cogent rep spam me using an email address that is _only_ used as an ARIN contact, trying to sell me bandwidth. When I called him out on it, with compliance@arin.net<mailto:compliance@arin.net> CCed, he backpedaled and claimed to obtain my information from Google. ARIN has repeatedly informed Cogent that their use of the ARIN Whois for solicitation is contrary to the terms of use and that they must stop. Despite ARIN’s multiple written demands to Cogent to cease these prohibited activities, ARIN has continued to receive complaints from registrants that Cogent continues to engage in these prohibited solicitation activities. For this reason, ARIN has suspended Cogent Communications’ use of ARIN’s Whois database effective today and continuing for a period of six months. For additional details please refer to https://www.arin.net/vault/about_us/corp_docs/20200106_whois_tos_violation.p... ARIN will restore Cogent’s access to the Whois database at an earlier time if Cogent meets certain conditions, including instructing its sales personnel not to engage in the prohibited solicitation activities. Given the otherwise general availability of ARIN Whois, it is quite possible that Cogent personnel may evade the suspension via various means and continue their solicitation. If that does occur, please inform us (via compliance@arin.net<mailto:compliance@arin.net>), as ARIN is prepared to extend the suspension and/or bring appropriate legal action.
