⚠️ This project is still experimental. Be very careful when using files generated from this for any kind of production use.
Free software projects that maintain a P2P network aim for diversity of peers to protect its users from partitioning and eclipse attacks. To achieve this, they sort peers into buckets. A primitive version of this is bucketing by /16 IP prefixes, but depending on the threat model of the project, bucketing by geographic location or ISP of the peer is more effective. These projects then rely on map files for this supplemental information that may come from providers that are malicious or compromized.
Kartograf is a free software project that generates such map files, for the start IP to AS maps, in a trust-minimized and transparent way. It pulls data from different public sources and combines them in a purely functional way to minimize the possibility of accidental BGP leaks or malicious hijacks ending up in the resulting map. Additionally, the software provides informative, easy-to-parse logging and preserves intermittent artifacts. Projects utilizing Kartograf will then publish this information which allows their users to audit the generation process of the map and verify the integrity of the shipped result file by repeating the process, similar to reproducible build systems.
The recommended method of installation is with Nix. You can read about why here. You may however install from any method below.
The Nix flake in this repo exposes a development shell, with the rpki-client binary, Python 3.10, and the Python packages required to run kartograf.
If you have Nix installed with flakes enabled, clone this repo, and run nix develop. You can now proceed to Usage.
If you don't have flakes enabled, you can either:
- pass the flag
--experimental-features 'nix-command flakes'whenever you runnix develop - or add the following line to
~/.config/nix/nix.conf:
experimental-features = nix-command flakes
to enable flakes in your Nix config, then run nix develop.
Kartograf requires rpki-client version 8.4 or higher to be installed locally. Many package managers have rpki-client, however please note that typically only the latest version is available. Kartograf is currently tested to work with rpki-client 8.4 - 9.3. If a new release is available that breaks compatibility, you may need to build a compatible rpki-client version yourself if your preferred package manager does not have a compatible version available. In that case, see the instructions in the rpki-client-portable project.
# Linux/BSD
$ {pkg,dnf,yum,apt} install rpki-client
# macOS
$ brew install rpki-client
Python versions 3.10, 3.11 and 3.12 have been tested with Kartograf.
You can use pip3 to install required Python packages:
$ pip3 install -r requirements.txt
Kartograf has not been tested on Windows.
To check whether you have all the dependencies required to use Kartograf, you can run the following from the root of the project directory:
python check.py
Please be aware that the full process currently takes about 6 hours with an M1 Macbook Pro and fiber optic connection.
Generate a fresh map of IP prefix to ASN using only RPKI:
./run map
You can enhance the RPKI maps with RIRs IRR data or Routeviews data using the -irr and -rv flags:
./run map -rv
This feature allows multiple contributors to launch the mapping process simultaneously which should result in mostly the same data for all of them, potentially even let some or all of them get the exact same result. this should improve confidence in the correctness of the data collected. A future timestamp that is coordinated between participants can be provided to the -w (--wait) option, the mapping process then launches at this exact moment and uses it also as the RPKI validation timestamp.
All other map building flags are compatible but not the reproduction flags.
./run map -w 1702299537 -rv -irr
This uses an pre-existing data folder and creates a map from it, allowing to reproduce map files. The posix timestamp needs to be provided as well and it needs to match the epoch of the initial run exactly, otherwise the resulting file will be different.
./run map -r /path/to/data -t 1698854940
This merges on map into another map. The mappings of the base file have preference over those in the extra file.
./run merge -b /path/to/base_file.txt -e /path/to/extra_file.txt -o /path/to/output.txt
Check the coverage of a given list of IPs for a given IP prefix to ASN map:
./run cov -m /path/to/map_file.txt -l /path/to/ip_list.txt
Kartograf expects files input files to be in the following formatting and also produces output files that follow this format.

In order to properly validate RPKI ROAs Kartograf downloads all RIR Trust Anchors via each users TAL. Usage of the ARIN TAL file requires users of Kartograf to agree to ARIN's Relying Party Agreement.
