Tools to create (and analyze) RIPE Atlas network measurements

Project description

This is a set of Python programs to start distributed Internet measurements on the network of RIPE Atlas probes, and to analyze their results.

For installation, you can use usual Python tools, for instance:

pip3 install blaeu

(On a Debian machine, the prerequitises are packages python3-pip, python3-openssl and python3-cymruwhois. On other systems, pip3 will install the dependencies.)

Usage requires a RIPE Atlas API key (which itself requires a RIPE account), and RIPE Atlas credits. If you don’t have a RIPE account, register first. Once you have an account, create a key, grant it the right to start new measurements, and put the key in ~/.atlas/auth. If you don’t have Atlas credits, host a probe,or become a LIR or ask a friend.

You can then use the four programs (-h will give you a complete list of their options):

  • blaeu-reach target-IP-address (test reachability of the target, like ping)
  • blaeu-traceroute target-IP-address (like traceroute)
  • blaeu-resolve name (use the DNS to resolve the name)
  • blaeu-cert name (display the PKIX certificate)

Blaeu requires Python 3.

Note that the old version ran on Python 2 but is no longer maintained. (It was partially documented at RIPE Labs.)


It comes from the famous Dutch cartographer. The logo of the project comes from his “Theatrum Orbis Terrarum” (see the source).
