1. HostedScan maintains a reverse DNS to scanners.hostedscan.com for all of our servers so that the IP addresses can be easily identified.

    You can get the full IP list with a command such as nslookup or online DNS lookup tools such as MXToolbox

  2. HostedScan also maintains an API endpoint returning a JSON array of the scanner IP addresses. This endpoint is public and does not require authentication: https://api.hostedscan.com/scanners
