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 C8 power connection.

Hardware specifications

The anchor consists of:

  • Soekris Net6501-70 board
  • 1U 19-inch rack-mounted case
  • Samsung 850 EVO 250GB mSATA SSD

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

Life-cycle replacement

The RIPE NCC is offering to support the anchor software for three years. We recommend that anchor hosts purchase the hardware with a service contract and extended warranty that will cover this three-year period. If anchor hosts want to continue using the service after this time, they will need to replace the hardware after three years. Otherwise, the service will be disabled by the RIPE NCC in order to guarantee optimum performance of the RIPE Atlas network. The three-year service contract with the RIPE NCC begins from the moment the anchor becomes public in the list of anchors and map of anchors.

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

Note: Due to Soekris - manufacturer behind RIPE Atlas V2 anchor hardware - suddenly announcing end of business, current applications will be held until the new RIPE Atlas V3 anchors are available. We expect to resume shipping in mid-September. More information here.

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. Consider the warranty offered, as there is a life cycle of three years, after which you will be requested to replace the hardware if you wish to continue with the service.

    Please read carefully the installation instructions about buying an anchor at your own reseller.

  2. Buy the hardware from one of the resellers listed below. In this case, you will receive the hardware pre-assembled and can take advantage of a discounted price that the RIPE NCC has negotiated. The assembled anchor hardware will come with a three-year warranty included in the final price.

Our resellers currently include:

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.
