Internet exchanges in Marseille
An exchange is a shared switch where networks hand traffic to each other directly. Participant counts come from PeeringDB, where each network maintains its own record.

What a Marseille IP address tells you
The two Marseille exchanges are close in size, with 110 participants at France-IX Marseille and 107 at DE-CIX Marseille, which together account for the city's 217 peers. Colocation is far more concentrated than peering. Of the 256 network presences PeeringDB counts across five facilities, 221 are in the Digital Realty Marseille MRS1/2/3/4 campus, 28 in Free Pro - Marseille - MRS1, and the remaining three buildings record seven between them. No mobile ASN belonging to Bouygues Telecom, Orange or SFR appears on either exchange participant list.
An address that geolocates to Marseille may have no device in Marseille behind it. Operators announce address blocks from a registry record that names one location for the entire allocation, and mobile traffic reaches the internet through a small set of gateways rather than from the cell the handset is attached to. Geolocation databases follow the operator's own published location, so the city they report is the operator's paperwork answer and not a measurement of where the connection started.
Anyone checking a Marseille address should read the origin ASN on the specific prefix before trusting the city. A prefix originated by a French mobile ASN (3215, 5410, 15557) marks mobile traffic wherever the handset is. A prefix originated by a network with colocation in the city is one of the 256 presences PeeringDB counts here, and the netname on the narrowest matching inetnum usually names the assignment holder more accurately than the city field does.
Mobile carriers in France
A mobile address in Marseille 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 Marseille?
Two are in PeeringDB. France-IX Marseille has 110 participants and DE-CIX Marseille has 107, for 217 peers across the city. Colocation is more concentrated than that, with five facilities holding 256 network presences and 221 of those inside the Digital Realty Marseille MRS1/2/3/4 campus.
Do French mobile carriers peer in Marseille?
The registry does not show it. Neither France-IX Marseille nor DE-CIX Marseille lists a mobile ASN for Bouygues Telecom, Orange or SFR among its participants. PeeringDB records public peering only, so a carrier can still interconnect privately in the city without appearing on either list.
Does an IP that geolocates to Marseille mean the device is there?
No. The city comes from the registry record for the address block, which names one location for an allocation that may serve a whole country. Mobile networks route subscribers through a few gateways. Read the origin ASN and the netname on the specific prefix instead.
