Amazon Prime NOC contact
by Adair Winter 30 Jul '23

30 Jul '23

I'm wondering if anyone from the Amazon Prime team might be hanging around or if anyone has a good contact? We are seeing a number of our CG-NAT subnets getting blocked with the "VPN" error, likely because they are seeing too many customers from the same or similar IP's. We'd like to talk to them about working through this or a whitelist or something. Thanks, -- Adair Winter AW Broadband A 203 SW 8Th Ave. Ste 601, Amarillo, Texas O 806.412.0888 <806-412-0888>M 806.231.7180 <806-231-7180>E adairw(a)awbb.net <adairw(a)awbb.net> W www.awbb.net <http://facebook.com/awbroadband>

Historical info on how 'x.com' came to be registered
by Drew Weaver 29 Jul '23

29 Jul '23

Does anyone have any historical information on how 'x.com' came to be registered even though single letters were reserved? Is there a story or is it as simple as it was registered prior to the reservation? Just wondering. Thanks, -Drew

Cogent Abuse - Bogus Propagation of ASN 36471
by Pete Rohrman 21 Jul '23

21 Jul '23

NANOG, A customer of Cogent has a compromised router that is announcing prefixes sourced from AS 36471. Cogent is propagating that to the world. Problem is, those prefixes and AS don't belong to that customer of Cogent - AS 36471 belongs to Kratos Defense & Security Solutions, Inc. (see whois). Requests to Cogent Support and Abuse go un-actioned. Need a contact at Cogent Abuse that can shut down that compromised router. Anyone have a good contact at Cogent Abuse Dept?

AWS hosted sites like slack unreachable
by Margi Varia 21 Jul '23

21 Jul '23

Hi Nanog, We are seeing this weird issue in one part of the network. Customers in one public subnet are not able to reach certain websites suddenly which are hosted in AWS like slack.com, bill.com.. We changed the subnet to new one and issue resolved, after 48 hours, we have the same issue again. We are not AWS customer, so can't call them, but what are our options? Thanks, Margi
