How can I fix an unreachable target?

A target is unreachable when HostedScan cannot connect to it. Fix a typo in the target, a site that is down, or a firewall or WAF that blocks the scanners.

Last updated on 28 Oct, 2026

An unreachable target is one where HostedScan was unable to establish the necessary connection for scanning. There are a few common reasons for this:

  1. A typo in the target. An invalid URL or a domain name without DNS records cannot be scanned. Fix: ensure that the URL, IP address, or fully qualified domain is correct.

  2. The website is not up. Fix: ensure that the website is running properly and you can open it in your browser.

  3. A network or firewall is blocking the traffic from the scanners. Fix: Configure your network to allow traffic from HostedScan. See https://help.hostedscan.com/help/what-ip-addresses-are-used-for-the-hostedscan-vulnerability-scanners for full details about the IP addresses used by HostedScan.

What IP addresses are used for the HostedScan vulnerability scanners?

HostedScan scanners run from the IP addresses behind scanners.hostedscan.com. Look them up with DNS or a public JSON endpoint, and allow them in your firewall.
