IP networks in use

You have to use a public network range to run an experiment between several Grid5000 sites.

Public networks

  • only some servers : 131.254.202.0/23

Routed private networks

  • computing : 172.16.96.0/20
  • virtual : 10.156.0.0/14

Experiment Network

  • Our network connectivity is provided by a single switch: a Cisco 6509. It provides us with a gigabit ethernet connection to each cluster node, a 10G uplink to Renater and a Gigabit uplink to the IRISA Network (used for DNS/NTP access, and connection to satellite sites).

Node names

  • Compute nodes must be reserved before use with OAR on frontend.rennes.grid5000.fr
