Become a RIPE Atlas Anchor Host

RIPE Atlas anchors play an integral role in the RIPE Atlas network by acting as enhanced probes with greater measurement capacity, as well as providing regional measurements by serving as co-operating targets for surrounding probes.

Before applying for an anchor

The anchor is designed to be installed in a highly-available network and physical environment, in order to operate as a stable measurement device and target. It is not suitable for use in a home network – instead, you should apply for a regular RIPE Atlas probe for use in a home network.

Network requirements

  • The anchor must have native IPv4 and IPv6 (if IPv6 is announced in the host ASN)
  • Static IPv4 and IPv6 addresses need to be unfiltered (not firewalled)
  • The anchor requires a single RJ45 network connection
  • The anchor may require up to 10 Mbit bandwidth (it currently requires much less)


Anchors are measurement targets, and therefore need to be reachable from any location on the Internet at all times, and are therefore designed to be placed in front of your network’s firewalls. By doing so, the anchor will not be able to access your firewalled network, which ensures your own network’s security.

The RIPE NCC remotely manages a firewall installed on the anchors and keeps them secure through regular security patches and updates. This is another reason we need to have unrestricted access to the anchors, along with the possibility of installing new functionality in the future.

If you have concerns regarding the security of RIPE Atlas anchors, please get in touch with us.

Physical requirements

The anchor is a 1U rack-mounted device with a single IEC C14 power connection.

Hardware specifications

The anchor consists of:

  • PC Engines APU2C2/APU2C4 system board
  • 1U 19-inch rack-mounted case
  • Samsung 850/860 EVO 250GB mSATA SSD
  • Power supply

It is useful if there is a serial port connection available for troubleshooting.

Life-cycle replacement

The RIPE NCC agrees to provide best efforts to keep the RIPE Atlas network up and running for at least the duration of the service provided to the Anchor Probe, which is set as the duration of the hardware service contract with the reseller or manufacturer.

Anchor hosts who wish to continue using the service after the warranty period expires may do so. However, hosts whose anchors are deemed to have failed will be prompted to replace their hardware. If the anchor is not replaced, the service will be disabled by the RIPE NCC in order to guarantee optimum performance of the RIPE Atlas network.

Agreement on Terms and Conditions and Memorandum of Understanding

To apply for an anchor you must agree to the RIPE Atlas Service Terms and Conditions and Memorandum of Understanding.

Apply for an anchor

Step 1 - Create a RIPE NCC Access account

If you don't already have a RIPE NCC Access account, please create one. By doing so, you'll become a member of the RIPE Atlas community and will be able to apply for an anchor.

Step 2 - Apply for an anchor

You can apply online to host a RIPE Atlas anchor. Once your request is approved by the RIPE NCC, you will receive an email with further instructions within a week. Once you have received this confirmation, you can purchase the necessary hardware.

Step 3 - Purchase an anchor

There are two options:

  1. Buy the hardware from your own reseller. Please make sure you order the exact hardware specified above. Do not order any part until you receive confirmation from the RIPE NCC that your request has been approved.

  2. Buy the hardware from one of the resellers listed below.


Please read the installation instructions carefully for anchors bought at Varia store, as the SSD will need to be replaced.

If you wish to become a reseller of the anchor hardware, please email atlas [at] ripe [dot] net

Step 4 - Installation and setup

Details about this step are in our installation instructions page.

Mailing lists

You can join the public mailing list for RIPE Atlas users (be advised that this is a public list which is archived). It can be used to give us your feedback and interact with other RIPE Atlas users. For more general discussions about Internet measurements with the RIPE community, the Measurement Analysis and Tools (MAT) Working Group Mailing List is available.
