Grenoble Internet eXchange or GrenoblIX is the Internet eXchange point (IXP) of Grenoble[1][2] in Isère and Auvergne – Rhône-Alpes region. GrenoblIX allows to the connected members to exchange the traffic in order to avoid passing by faraway infrastructures.[3][4] This Internet eXchange point is managed by the non-profit organization Rezopole, founded in 2001.[5][6]

GrenoblIX is a GIX-NAP :

  • the GIX, to exchange IP packets or peering[7] (the exchange can be done on the level 2– BGP – or on the level 3 by « Routes Servers ») ;
  • the NAP (Network Access point), for a market place which allows members to buy or sell Internet transit and/or any layer 2 or IP services and all the types of Telecommunications services.


GrenoblIX, contraction of Grenoble and GIX[8] (Global Internet eXchange), is a name of the Internet eXchange point (IXP) of Grenoble in Isère and Auvergne – Rhône-Alpes region.

GrenoblIX is 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.[9][10] The last site is particular as it is considered as the first eco-friendly datacenter in France.[11][12]


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 passing by faraway infrastructures.


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

The members connected to IXP NAP are :

  • ISP (Internet service provider)
  • Internet operators for companies
  • datacenters
  • e-commerce websites
  • large private companies
  • large public institutions
