GrenoblIX

Grenoble Internet eXchange or GrenoblIX is the Internet eXchange point (IXP) of Grenoble in Isère and Auvergne – Rhône-Alpes region. GrenoblIX allows to the connected members to exchange traffic in order to avoid routing through faraway infrastructures. This Internet eXchange point is managed by the non-profit organization Rezopole, founded in 2001.

GrenoblIX is a GIX-NAP:
 * the GIX, to exchange IP packets or peering (the exchange can be done on level 2 – BGP – or on level 3 by "route servers");
 * the NAP (Network Access point), for a marketplace which allows members to buy or sell Internet transit and/or any layer 2 or IP services and all types of telecommunications services.

Origin
GrenoblIX, a contraction of Grenoble and GIX (Global Internet eXchange), is the name of the Internet eXchange point (IXP) of Grenoble in Isère and Auvergne – Rhône-Alpes region.

GrenoblIX was founded in Grenoble in April 2011 by the non-profit organization Rezopole. It operates two sites: GrenoblIX 1 located in the COGENT datacenter, and GrenoblIX 2 located in the Eolas groupe datacenter. The last site is particular as it is considered as the first eco-friendly datacenter in France.

Functioning
An IXP gives users the capacity to exchange Internet traffic through peering. The members can improve the quality of their bandwidth and avoid additional costs. The IXP is an important factor to develop the local Internet: the members located in the same area can exchange traffic locally instead of routing through remote infrastructure.

Any person having an Autonomous System number can be connected to GrenoblIX.

The members connected to IXP NAP are:
 * ISPs (Internet service providers)
 * Internet operators for companies
