SFINX, the first IXP in France, was established in 1995 and hosted by the French academic and research network, RENATER (Réseau National de Télécommunications pour la Technologie, l’Enseignement et la Recherche). The exchange has 2 POPs in Paris interconnected by two 10 gigabit Ethernet links. With 90 members, peak traffic runs at about 28Gbps.

SFINX provides VLAN services and also hosts an NTP server as well as domain name mirrors for three root servers and four AFNIC DNS servers. RENATER’s CERT service is also strongly supported by SFINX.


France-IX is the largest IXP in France with 223 members and about 220 Gbps of peak traffic. France-IX's infrastructure consists of 7 PoPs in Paris and 1PoP in Marseille, using Brocade and Force 10 equipment.

France-IX also operates its own links to a number of neighbouring IXPs (SFINX, LyonIX, LU-CIX (Luxembourg), Top-IX (Italy), TouIX (Toulouse), etc.). France-IX members may use these links for connections of up to 100Mbps after which they need to purchase their own links.

LyonIX, GrenoblIX, SaintetIX and ADN-IX

These four exchanges, in Lyon, Grenoble, Saint Etienne and Valence are managed by the non-profit group Rezopole. LyonIX was the first and is the largest of the four, established in 2001 by a group of Internet pioneers who subsequently formed the Rezopole group to promote connectivity in the Rhone-Alps region.

LyonIX has two POPs providing service to 80 members. Aside from peering services, it also provides to its members dark fibre and wavelengths between its POPs as well as hosting services, DNS resources for a number of TLDs, NTP synchronisation, RPKI facilities, ftp servers, and open-source software mirrors. LyonIX also provides a link to the Italian IXP network, Top-IX.

Services are also provided to the general public, including video conferencing, data storage (up to 1Gb), ftp for up to 10 files, a Google Maps API, an RDV meeting scheduler, and group document editing. The LyonIX website is notable in displaying a map showing the location of each of its members and POPs.

SaintetIX was set up in 2009, while GrenoblIX and ADN-IX were established in 2012. GrenoblIX has two POPs and currently has three members while the other two exchanges each have two members.

In Strasbourg, the IXP is called EuroGix.  It is intended to be a cross-border IXP for the upper Rhine basin and currently has 5 members.

Fr-IX is operated as a co-operative called Opdop and has 18 members. Its mission is to support the development of local Internet providers. Fr-IX has a presence in Paris (6 sites), Rennes, Le Mans and Marseille. Fr-IX provides route-server access but does not offer private peering or VLAN services.
