Article 1 – Definitions

In these Terms and Conditions, the following terms shall be understood to have the meanings assigned to them below:   RIPE NCC - Réseaux IP Européens Network Coordination Centre, a membership association under Dutch law, with a registered office in Amsterdam, the Netherlands.

RIPE Atlas Service – A RIPE NCC service that provides a measurement platform using RIPE Atlas Data collected by active Probes and Anchors around the world.

RIPE Atlas Portal – The webpages of the RIPE Atlas website accessible through a User’s credentials.

API – Application Programmable Interface that allows Users to perform measurements and access their Probe details, Credits information and Results.

Probe – A hardware device with embedded software that makes active traffic measurements and observes responses for the purposes of the RIPE Atlas Service.

Anchor – A hardware device or virtual machine that performs as a Probe and has additional functionalities as a target.

Probe Host – A natural person or a legal entity that has a Probe or an Anchor Probe registered with the intention that it be installed in a network.

User – A person who has access through their personal credentials to the RIPE Atlas Portal and API and may perform Measurements. This includes Probe Hosts.

Measurement – A request for, and the execution of, a set of observations, with a given set of properties (time period, flags, etc.), towards a single target, involving one or more Probes. Measurements can be requested either by using the RIPE Atlas Portal or API command, authenticated with the key generated by the User.

Result – A simple data point collected by the RIPE Atlas Service, consisting of a source IP address or hostname, destination IP address or hostname, measurement type, timestamp and observation (and other optional attributes).

RIPE Atlas Data – Data collected via RIPE Atlas including Probe network parameters, Measurements and Results.

Credit – A metric unit used in the RIPE Atlas Service. Credits may be earned and spent by Users in accordance with the Credit System described at

Article 2 – General

2.1. The Terms and Conditions come into effect by means of offer by the RIPE NCC and an acceptance by the User.

2.2. By receiving a Probe, the Probe Host confirms that they have read, understood and agree to be bound by these Terms and Conditions for every future use of the RIPE Atlas Service. By accessing the RIPE Atlas Service, the User confirms that they have read, understood and agree to be bound by these Terms and Conditions for every future use of the RIPE Atlas Service. If the User does not accept these Terms and Conditions, they shall not make use of the RIPE Atlas Service. The use of the RIPE Atlas Service is subject to these Terms and Conditions and implies full acceptance by the User.

2.3. The User acknowledges and accepts that the Terms and Conditions may be amended by the RIPE NCC. The RIPE NCC will inform the User of such amendments at least 30 days before the amendments become effective. If the User continues to use the RIPE Atlas Service after the amendments become effective, the User agrees to the amended Terms and Conditions.

2.4. These Terms and Conditions prevail over explanatory documents and any text regarding the RIPE Atlas Service, which exist for guidance and informational purposes only and do not affect the interpretation of these Terms and Conditions. 2.5. These Terms and Conditions replace any and all existing agreements between the RIPE NCC and the User with regard to the RIPE Atlas Service.

Article 3 – Use of RIPE Atlas Service

3.1. The RIPE Atlas Service is a measurement platform for purposes such as research, network monitoring, network debugging and alerting about network events (hereafter referred to as the purposes of the RIPE Atlas Service).

3.2. Subject to these Terms and Conditions, Users may create their own Measurements via the RIPE Atlas Portal or the RIPE Atlas API. The RIPE NCC may create its own Measurements, for the purposes as mentioned in Article 3.1, towards targets of value for some important Internet infrastructure. Measurements may be performed by any Probe and may include any Probe.

3.3. Users are entitled to perform Measurements provided they have sufficient Credits and provided the Measurements are reasonable in terms of resource usage.

3.4 For the purposes of the use of the RIPE Atlas Service, Users are required to register and maintain a valid email address and contact details in the RIPE Atlas Portal.

Article 4 – Publication and Use of RIPE Atlas Data

4.1. The RIPE NCC will publish the RIPE Atlas Data in various forms and make this available via (hereafter “RIPE NCC website”) as well as the RIPE Atlas API.

4.2. Users agree that the RIPE Atlas Data collected by the Probe(s) they host may be publicly available. The User may select the option to not make their RIPE Atlas Data publicly available, in which case the RIPE NCC shall exclude their RIPE Atlas Data from being indexed in the RIPE NCC website or the RIPE Atlas API, although their RIPE Atlas Data will still be publicly available in aggregated form. In any case, if a Measurement is performed by several Probes, this Measurement will be visible to the Hosts of the Probes involved in this Measurement.

4.3. Probe Hosts agree that their Probe network parameters (i.e. non-RFC1918 IP addresses, RFC1918 addresses if their probe is behind a NAT, “shared address space” addresses if their probe is behind a double NAT (CGN) (RFC6598), and hostnames given to those IP addresses in DNS) will be visible in the Results of any Measurements created using their Probe.

4.4. The name and contact details of Probe Hosts and of the Users involved in a particular Measurement will not be publicly available unless explicitly allowed by them. Configuration settings, MAC addresses, DNS entries of Probes and the email addresses of Probe Hosts will not be publicly available.

4.5. Users agree to make responsible use of the RIPE Atlas Data in line with the purposes of the RIPE Atlas Service as mentioned in Article 3.1. Users may perform research using RIPE Atlas Data, and they can notify the RIPE NCC about the results of this research by sending an email to Any commercial use of the RIPE Atlas Data is subject to prior permission by the RIPE NCC.

4.6. The RIPE NCC is entitled to retrieve, reproduce, make available, store and combine RIPE Atlas Data obtained through the RIPE Atlas Service for the purposes of the RIPE Atlas Service. The RIPE NCC, at its own discretion, will analyse the RIPE Atlas Data and make the Results publicly available on the RIPE NCC website.

4.7. The RIPE NCC may provide RIPE Atlas Data and analysis of RIPE Atlas Data to third parties for scientific and statistical purposes. This provision may continue even after the RIPE Atlas Service is no longer available.

Article 5 – Use of Probes

5.1. Subject to these Terms and Conditions, the Probe Host shall receive and install a Probe on a network. The Probe Host must have obtained clear prior permission for the connection and use of the Probe in this network if the network is not the Probe Host’s home network.

5.2. The Probe Host shall register the Probe with correct and valid data in the RIPE Atlas Portal. The Probe Host shall ensure the data submitted via the RIPE Atlas Portal is valid at all times.

5.3. Subject to these Terms and Conditions, the Probe Host may use the Probe and any other Probes in order to perform Measurements and obtain Results via the RIPE Atlas Portal.

5.4. The Probe Host agrees that other Users may perform their own Measurements using his/her Probe. The RIPE NCC will keep a record of all Measurements created involving that Probe. This record will be available to the Probe Host at any time.

5.5. The Probe Host shall make a best effort to keep the Probe connected to the Internet at all times. If the Probe Host wants to disconnect the Probe indefinitely they must notify the RIPE NCC and the RIPE NCC will try to make arrangements to find a new host for the Probe.

5.6. The Probe Host shall not interfere with the Measurements performed via their Probe, shall not try to disassemble the Probe and shall not tamper with it or harm it in any other way.
