ASN Whois Database

Overview

Our ASN WHOIS (parsed) Database provides clean, normalized ownership and contact intelligence for Autonomous System Numbers worldwide. Instantly see who operates an ASN, where it’s registered, and how to reach the right people, so you can validate routing policies, accelerate incident response, enrich threat intelligence, and keep network inventories accurate across security and NetOps workflows.

Updated daily and standardized across all RIRs (ARIN, RIPE NCC, APNIC, LACNIC, AFRINIC). Delivered in flexible formats (CSV, JSON, MMDB or custom exports/API). Below, you'll find full documentation of the archive contents, schema definitions, file specifications, and integration notes to help you get up and running quickly.

4. File Relationship Diagram

The diagram below illustrates the relationships between the various files included in the CSV database package. It shows how the main CSV file connects to reference tables for person and organization handle files, ensuring consistent and accurate data across for all the records.

File Format & Encoding

All ASN Whois CSV datasets are provided in UTF-8 encoding, comma-separated, and compressed with Gzip (.csv.gz). Each file includes a header row listing the field names for clarity and consistency.

Field values are unquoted by default, with quotes applied only in the following cases:

Line breaks within text fields.
Commas inside a value (e.g., addresses).
Lists of values (e.g., languages).
Spaces that may be auto-quoted by export tools.

JSON Database Documentation

1. Overview

JSON version of the database consists of two files: one JSON file containing all the data (organization and contact handle details), a README file, and a checksum file, and one checksum file, all compressed together in a ZIP file for easy delivery.

2. Archive Content

After downloading and extracting the ASN Whois MMDB database archive, you'll find the following files (with their types noted):

db-asn-whois.json.gz

Full WHOIS details for ASN: name, country, domain, RIR, contact IDs, and raw WHOIS record.

File Size: 47.34 MB

Entries: 130.0K

README.md

Documentation for dataset contents, schema, usage, and support.

File Size: 9.70 KB

checksum.txt

SHA-256 checksums for verifying file integrity.

File Size: 163 Bytes

Response Schema

This section describes the structure of the data returned from the ASN Whois MMDB file. Each field is detailed with its type, meaning, and example values to help you interpret responses and integrate them into your applications.

This file contains detailed WHOIS mappings for both IPv4 and IPv6 address ranges. Below is an example of the structure you'll find in the response.

2. Field Reference

The following reference lists all fields available in the JSON response. Each entry includes the field path, its description, data type, and example value to help you understand how to parse and integrate the data.

Database Integrity & Authenticity Verification

There are two methods of verifying the integrity and authenticity of our Database:

1. Using the Signature File (Recommended)

IPGeolocation.io signs every database release to ensure its authenticity and integrity. This allows customers to verify that a downloaded ASN Whois database file originates directly from IPGeolocation.io and has not been altered, corrupted, or tampered with during transfer or storage.

Each database update includes a corresponding signature file, generated using our private signing key. Customers can validate the database using the provided public verification key. To verify a database file, you need:

Database file (the downloaded archive)
Signature file (the matching signature for that archive)
Public key (public-key.pem)

These files are available via official IPGeolocation.io download endpoints and are also shared in database update notifications.

Tip

The public key may be provided as PEM-encoded text. Save it to a file named public-key.pem

Ensure OpenSSL is installed on your system. If not, install it using the following commands

On Linux, if openssl is not installed

sudo apt install openssl

Verify OpenSSL installation:

openssl version

To verify the database file, run the following command, replacing the placeholders with your actual file paths:

openssl dgst -sha256 -verify <path-to-public-key.pem> -signature <path-to-signature-file.sig> <path-to-database-file.zip>

Example output:

Verified OK

if verification FAILED do not use the file, re-download the database and signature from official IPGeolocation endpoints. If the issue persists, please contact our support team.

2. Using the Checksum File (Legacy)

Each database archive includes a checksum.txt file containing the SHA-256 checksums for the files packaged in the archive. You can use this file to validate that the extracted contents are complete and unchanged.

Note

Always verify downloaded files with the provided checksum before importing.

On Linux, if sha256sum is not installed, first run:

sudo apt-get install coreutils

Then check the archive files against the checksum file with:

sha256sum -c checksum.txt

Example output:

db-asn-whois.csv.gz: OK
db-org-details.csv.gz: OK
db-handles-details.csv.gz: OK
db-asn-whois.json.gz: OK
README.md: OK

*your output may differ depending on the specific database archive you downloaded.

If a file's checksum does not match, FAILED will be shown instead of OK . If verification fails, first confirm that the download completed correctly; if the issue persists, please contact our support team.

Data Format & Constraints

All fields defined in the schema are always present in the ASN Whois JSON response.
Fields may contain empty strings (""), but never null, so null checks are not required.
Place names such as countries, states, districts, and cities are available in multiple translations.
All text values are encoded in UTF-8.
Field names and response structure remain stable across updates for backward compatibility.

Database Updates & Delivery

When you subscribe to our ASN Whois database, we'll send you static download links. These links never change, so you can use them both for your initial download and for all future updates. You will receive:

Database Archive URL : downloads the latest release of your subscribed database (CSV, MMDB or requested formats).
Signature File URL : downloads the matching signature file for the latest release (used for authenticity verification).
Public Key URL : downloads the public verification key (used with the signature file).
Status Endpoint URL : returns the database's most recent update timestamp.

Our databases are refreshed daily and weekly, ensuring you always have access to the most current data. Each time your subscribed dataset is updated, you'll also receive an email notification so you don't miss a release.

For automated workflows, you can check our status endpoint to see the last update timestamp. When the date changes, simply re-fetch the archive using your static download URL to pull the latest version into your system.
