What a Dusseldorf IP address tells you
Dusseldorf's 644 peering records spread across seven exchanges rather than one. DE-CIX Dusseldorf has 207 participants, LOCIX DUSSELDORF 187, BGP.Exchange - Dusseldorf 147 and MegaIX Dusseldorf 94, while three smaller exchanges list five participants or fewer. Colocation is smaller in comparison, 321 network presences over 14 facilities, with Digital Realty Dusseldorf DUS1-3 at 138 networks and the WIIT DUS1-DUS7 site at 102. O2 (AS6805) peers at DE-CIX Dusseldorf, and PeeringDB does not record Deutsche Telekom or Vodafone mobile ASNs on the city's exchanges.
An address that geolocates to Dusseldorf may belong to a device anywhere in Germany. Operators announce address blocks from a registry record that carries one administrative address, and mobile subscribers reach the internet through a limited set of gateways, so a single city can stand in for traffic from a wide area. Commercial geolocation databases copy the operator's own published location for the block, which is why the answer follows the allocation rather than the cell the phone is attached to.
The origin ASN on a Dusseldorf address is more informative than the city name. It separates mobile ranges, such as O2's AS6805, from the hosting and enterprise networks that account for much of the 321 facility presences here. The netname and registry entry on the specific prefix say what the block was assigned for, and whether that assignment covers one site or a national pool.
Mobile carriers in Germany
A mobile address in Dusseldorf is routed by one of the country's operators. Each entry lists the operator's ASNs, so you can check which network an address belongs to.
Questions
Which internet exchanges are in Dusseldorf?
PeeringDB lists seven. DE-CIX Dusseldorf has 207 participants, LOCIX DUSSELDORF 187, BGP.Exchange - Dusseldorf 147 and MegaIX Dusseldorf 94. SBIX Dusseldorf, GL-IX and Schleyer-IX each record five participants or fewer. The city also holds 14 facilities with 321 network presences.
Do German mobile carriers peer in Dusseldorf?
O2 (AS6805) appears on DE-CIX Dusseldorf. PeeringDB does not record Deutsche Telekom (AS3320) or Vodafone (AS3209) mobile ASNs on any Dusseldorf exchange, which means their traffic reaches the city over transit or private links instead.
Does an IP that geolocates to Dusseldorf mean the device is there?
No. Geolocation databases follow the address the operator published for the block, and mobile traffic exits through a small number of gateways. A Dusseldorf reading is a reasonable guess about the operator behind the prefix, not proof of the device's position.
