Setting up User Login Restriction by IP Address
To restrict the use of an IP address for a technician, perform the following steps:
- Navigate to Administration → Accounts → Security settings. Click Add in the Technician allowed IP addresses widget.

In the Add IP restriction modal, enter one or more IP addresses for restriction in their Classless Inter-Domain Routing (CIDR) format. Click Enter on your keyboard between each entry.

Figure 2: Enter IP address or CIDR - NinjaOne supports multiple subnet masks; however, but does not permit the use of wildcards.
- Resources for translating an IP range to CIDR can be found in the CIDR to IPv4 Documentation (external link).
- Once IP address settings are changed, they take immediate effect.
- Click Save.
Reviewing IP Address Usage
To view which IP addresses technicians have used to log in, perform the following steps:
- Navigate to the System Dashboard, move your cursor over the Activities tab, and click All.

- Select the technician name from the User filter drop-down menu and extend the date range as needed.
- Look for Technician Logged In in the Status column and then review the Description field for that row to review the IP address used.
