| 65535:666 | BLACKHOLE (RFC 7999) | customers only | On a host route (/32 or /128) inside the customer's own space, every PoP drops traffic to that address. A tagged route of any other length is carried normally. ewr0 and ams0 also pass it to their upstream tagged 20473:666 alone, so it is dropped there too. Nothing else carries it out of AS46307. |

46307:1000 plus the location number read as hex: ewr0 is 10, so 1016. No upstream tags location, so AS46307 does. Visible in the bgp.tools feed.
