How to Add Geofeed to ARIN — Step-by-Step Guide

Adding Geofeed to ARIN

ARIN (American Registry for Internet Numbers) supports geofeed through the Comments field on NetRange and NetBlock objects. While ARIN doesn't have a dedicated geofeed attribute like RIPE, the standard RFC 8805 remarks format is fully supported and recognized by all major geolocation databases.

Prerequisites

An ARIN Online account with authority over the relevant NetRange/NetBlock
A geofeed CSV file hosted on a publicly accessible HTTPS URL
Your IP prefix must be registered in ARIN's Whois database

Step 1: Log In to ARIN Online

Go to ARIN Online
Log in with your ARIN credentials
Navigate to Your Records → Resources

Step 2: Find Your Network Object

Locate the NetRange or NetBlock you want to update
Click on the network to view its details
Click "Modify" or "Edit"

Step 3: Add Geofeed to the Comments Field

In the Comments (or Public Comments) field, add the following line:

Geofeed https://yourdomain.com/.well-known/geofeed.csv

💡 Important: The format must be exactly Geofeed (capital G) followed by a space and the HTTPS URL. This is the RFC 8805 standard format that geolocation databases look for.

Step 4: Submit the Changes

Review your changes
Submit the modification request
ARIN will process the update (usually within minutes for comment changes)

Step 5: Verify

Check your Whois record to confirm the comment has been added:

whois -h whois.arin.net 192.0.2.0

You should see your geofeed URL in the comments section. Allow 24-72 hours for geolocation databases to update.

Alternative: ARIN's GeoIP Correction Form

In addition to geofeed, ARIN provides a GeoIP correction process that can be used alongside geofeed for faster results.
