Re: FYI - Suspension of Cogent access to ARIN Whois

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?

Well, they would certainly be blocked by RPKI unless ROA's for those originations are created. Mark.
