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.
Available Database Formats
CSV Database Documentation
1.Overview
The CSV version is a set of Gzip-compressed CSV files containing ASN and ASN WHOIS information. These files are designed for bulk imports and integration into relational databases.
2.Archive Content
After downloading and extracting the ASN Whois CSV database archive, you’ll find the following files (with their types noted):
Links asBlock and autNum to WHOIS details: name, country, domain, RIR, and a raw WHOIS record.
Links an organization ID to its handle, name, type, and contact details.
Links the network handle ID to its name, country, address, and contact details.
Full WHOIS details for ASN: name, country, domain, RIR, contact IDs, and raw WHOIS record.
Documentation for dataset contents, schema, usage, and support.
SHA-256 checksums for verifying file integrity.
Always verify downloaded files with the provided checksum before importing.
On Linux, if sha256sum is not installed, first run:
sudo apt-get install coreutilsThen check the archive files against the checksum file with:
sha256sum -c checksum.txtExample 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: OKIf 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.
Schema
This section describes the schema of each file included in the ASN Whois Database archive. For every file, you’ll find its purpose, field definitions, and examples to help with integration.
1.db-asn-whois.csv.gz
This file contains detailed WHOIS information for Autonomous System Numbers (ASNs). It maps each AS Block and autNum to the name, country, domain, and RIR, as well as different contact handle IDs and the full rawWhois record.

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):
Full WHOIS details for ASN: name, country, domain, RIR, contact IDs, and raw WHOIS record.
Documentation for dataset contents, schema, usage, and support.
SHA-256 checksums for verifying file integrity.
Always verify downloaded files with the provided checksum before importing.
On Linux, if sha256sum is not installed, first run:
sudo apt-get install coreutilsThen check the archive files against the checksum file with:
sha256sum -c checksum.txtExample output:
db-asn-whois.json.gz: OK
README.md: OKIf 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.
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.
1.db-asn-whois.json
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.

}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 for the archive in your chosen formats. These links never change, so you can use them both for your initial download and for all future updates.
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.
