Re: AS16512 Unauthorized Announcement by Lumen

Austin, This prefix isn't being announced by Lumen, it is merely in their IRR db. This is quite different from your accusation of "unauthorized announcement". Stale IRR entries are very common and usually cause no issue on their own. These should be cleaned up to avoid any accidents but that

Re: backbones filtering unsanctioned sites

Cogent also have a blackhole route-server that they will provide to you to announce /32's for blackholing. The address for this is 66.28.1.228 which is the originator for the 104.31.19.30/3 2 and 104.31.18.30/32 routes. On 10 February 2017 at 18:46, Jason Rokeach

Netflix IP Space
