Enable ASN Lookup - Pangolin Docs

Try free on Pangolin Cloud

Fastest way to get started with Pangolin using the hosted control plane. No credit card required.

Pangolin uses an ASN database to map request IP addresses to autonomous systems, such as cloud providers, residential ISPs, VPN providers, and corporate networks. That ASN data powers ASN access rules and ASN blocking patterns. To enable ASN lookup features in Pangolin self-hosted, download the MaxMind ASN database, place it in the config/ directory, and point Pangolin at the database file. This can be done for free.

Remember to keep the ASN database updated regularly, as ASN assignments and network mappings can change over time. You can just repeat the download and extraction steps periodically to ensure your database is current.

You can automate this process with a MaxMind Docker container. See the GeoLite2 Automation community guide for an example.

Install with the Installer

You can use the installer to download and place the database for you. Download the latest installer:

curl -fsSL https://static.pangolin.net/get-installer.sh | bash

Then run the installer again:

./installer

Manual Installation

Download and extract the ASN database

Download and extract the GeoLite2 ASN database using the following commands:

# Download the GeoLite2 ASN database
curl -L -o GeoLite2-ASN.tar.gz https://github.com/GitSquared/node-geolite2-redist/raw/refs/heads/master/redist/GeoLite2-ASN.tar.gz

# Extract the database
tar -xzf GeoLite2-ASN.tar.gz

# Move the .mmdb file to the config directory
mv GeoLite2-ASN_*/GeoLite2-ASN.mmdb config/

# Clean up the downloaded files
rm -rf GeoLite2-ASN.tar.gz GeoLite2-ASN_*

Update the Pangolin config file

Update your Pangolin configuration to point to the new ASN database file. Edit config/config.yml to include the following entry:

server:
  maxmind_asn_path: "./config/GeoLite2-ASN.mmdb"

Restart Pangolin

Restart your Pangolin instance to apply the changes:

docker compose restart pangolin

Alternatively, you can create an account at MaxMind to get a license key and download the database directly from them.

After the ASN lookup database is enabled, use access control rules or the ASN Blocking guide to create blocking or allow rules.
