Combined from the evidence below: an ASN seen between AS39040 and the collectors (or inferred to be on the collector side) is listed as upstream; one seen behind it (“right”) as downstream.
1. Observed path adjacencies
ASNs that appear immediately next to AS39040 in AS paths seen by route collectors (prepends collapsed). These are path adjacencies, not confirmed BGP sessions, and the position says nothing certain about the commercial relationship.
| ASN | Position in path | Paths | Collectors | Example path | Last observed |

2. Direct sessions with route collectors
BGP sessions between AS39040 itself and a route collector (the AS feeds its routes to the collector).
AS39040 has no direct session with a route collector in the data.
3. Inferred neighbours
Neighbours inferred from AS paths seen by route collectors. “Left” neighbours appear between AS39040 and the collector, “right” neighbours on the origin side. These are inferences, not confirmed relationships.

- Path adjacencies are derived from route collector AS paths for 2 of 2 prefixes originated by AS39040. Appearing next to AS39040 in a path does not by itself confirm a direct BGP session or its commercial relationship.
- Inferred neighbours come from AS paths seen by route collectors: 'left' neighbours appear between AS39040 and the collectors (likely upstreams), 'right' neighbours appear behind it.
