Inferred from path position, not from any declaration by either party. A network appearing here is carrying these routes; whether that is a paid transit arrangement, a backup, or something else is not something routing data can tell you.

Adjacency is not the same as peering. Being next to each other in a path covers paid transit, settlement-free peering and customer connections alike, and routing data cannot distinguish them. Treat this as "these networks exchange routes", nothing more specific.
Interconnection
Exchange presence
Internet exchanges where Packet Clearing House has a port recorded for AS42184, largest fabric first. An exchange is shared switching where networks interconnect directly rather than paying a transit provider to carry traffic between them, so turning up at one is a deliberate choice about how this network wants to be reached. Each name opens that exchange's own page, with its peering LANs and every other network recorded on it. Recorded at 6 exchanges across 3 countries and 1 region.
| Exchange | Location | Their address | Member ports |
|---|---|---|---|
| DE-CIX Frankfurt | Frankfurt, Germany | 80.81.192.178 | 1,073 |
| AMS-IX Amsterdam | Amsterdam, Netherlands | 80.249.210.6 | 894 |
| DE-CIX Dusseldorf | Düsseldorf, Germany | 185.1.170.16 | 226 |
| Peering.cz | Prague, Czech Republic | 185.0.21.15 | 212 |
| DE-CIX Munich | Munich, Germany | 185.1.208.147 | 207 |
| DE-CIX Hamburg | Hamburg, Germany | 185.1.210.102 | 195 |
Unlike the tables above, this is recorded rather than inferred. An address on a peering LAN is at that exchange by definition. Two carve-outs all the same. Member ports counts every participant at the exchange, not this network's ports, so read it as a size proxy. And an absent exchange means PCH has no record of it, not that the network is not there.
Provenance
Where this comes from
Derived from routing tables collected at 2026-08-09 10:00 UTC by route-views2,rrc00, as seen from 75 BGP vantage points across 74.03M route entries. These are observations from those vantage points, not a complete or authoritative view of the internet.
Cross-check against RIPEstat or BGP.tools, which observe from a different and larger set of vantage points.
Exchange presence comes from a separate dataset: the directory collected 2026-08-09 by Packet Clearing House (https://www.pch.net/ixp/data), covering 1,327 exchanges and 93,164 recorded member ports, licensed CC BY-NC-SA 3.0.
PeeringDB is the better-known directory and is deliberately not the source here: its acceptable-use policy forbids the bulk storage this needs. The two answer different questions anyway. PeeringDB reports what an operator declares about itself; this reports what PCH has recorded.
