Freely accessible information services can be used by all users, regardless of the IP range.

When using electronic resources, please note the following:

Network-dependent access


Direct access is only possible from the main networks of ETH Zurich (in some cases proxy still required):

  • 129.132.0.0 bis 129.132.255.255
  • 82.130.64.0 bis 82.130.127.255

In all other cases, Public VPN or alternatively proxy.ethz.ch must be used.

Check whether the IP address for your computer is within the ETH Zurich network structure: Check your IP address

For access via an external provider (ADSL, Cablecom, iPass) you should also use Public VPN or proxy.ethz.ch.
