The purpose of this document is to provide 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) 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.
