This document provides Outpost24 network scanning range information. 


To avoid interference with Firewalls, Intrusion Detection Systems (IDS), and Intrusion Prevention Systems (IPS) it is recommend to set up OUTSCAN within a trusted range.

Network Scanning Range

Firewalls, IDSs and IPSs may interfere with the security scan if they have a reactive defense mechanism. In such case, we recommend to set up OUTSCAN (CIDR IP range,, IPv6 range 2001:67c:1084::/48, 2a13:5240::/29) as a trusted range.


The scanning occurs from within the below range:

  • For IPv4: to, to
  • For IPv6: 2001:67c:1084::0 to 2001:067c:1084:ffff:ffff:ffff:ffff:ffff, 2a13:5240::0 to 2a13:5240:ffff:ffff:ffff:ffff:ffff:ffff.
