Frequently Asked Questions
Why doesn't the app use ICMP ping?
Wolf IP Scanner runs inside the macOS App Sandbox, which does not allow raw socket access. ICMP (the protocol used by the traditional ping command) requires raw sockets. Instead, the app uses TCP connect timing — connecting to open ports and measuring round-trip time — which provides an equivalent latency measurement without requiring special privileges.
Why can't I see MAC addresses?
MAC address resolution requires ARP table access via the arp command or raw network sockets, neither of which is permitted in the App Sandbox. MAC address discovery is therefore not available in the Mac App Store version of Wolf IP Scanner.
How does Traceroute work in the app?
True hop-by-hop traceroute requires sending packets with specific TTL (Time To Live) values using raw ICMP sockets — not permitted in the App Sandbox. The in-app Traceroute performs TCP latency probes to the target host. For a full hop-by-hop trace, use the Copy Command button in the Traceroute panel to copy the native command and paste it into Terminal.
The scan doesn't find some devices on my network. Why?
Some devices may not be detected because:
  • They have no open TCP ports (Wolf IP Scanner detects hosts via TCP, not ICMP).
  • A firewall is blocking all inbound connections to the device.
  • The device uses a power-saving mode that closes all ports when idle.
  • The IP range you scanned doesn't include the device's address.
Try switching to the Full scan preset, which checks a larger set of ports, or use a Custom preset to target specific ports you know the device listens on.
How do I scan a range other than my local subnet?
In the scan toolbar, type any IP range in CIDR notation (e.g. 10.0.0.0/24) or a start–end range (e.g. 192.168.0.1-192.168.0.50). Wolf IP Scanner will scan only the addresses you specify.
What SNMP community string should I use?
The default SNMP read community string is public, which works for most unconfigured routers and switches. If your device has a custom community string, enter it in the Community field in the SNMP panel before querying. Wolf IP Scanner supports SNMP v2c only.
Can I automate scans?
Yes. Open the Schedule popover in the toolbar and choose an interval: every 5, 15, or 30 minutes, or every 1 or 2 hours. The app will scan automatically and show a system notification when new devices appear or disappear.
How do I export scan results?
Go to Wolf Scanner › Export in the menu bar and choose CSV, XML, or HTML. You can also import a previously exported file via Wolf Scanner › Import Scan….
Does Wolf IP Scanner collect any personal data?
No. Wolf IP Scanner does not collect, store, or transmit any personal data, network data, or usage information. All scanning activity happens entirely on your device. We do not use analytics, crash reporting services, or any third-party SDKs.
Privacy Policy

Data collection: Wolf IP Scanner collects no personal data whatsoever. No account is required. No information is sent to our servers or any third party.

Network access: The app connects only to IP addresses and hosts you explicitly ask it to scan. All connections are outbound and initiated by you.

Local storage: Tags, port history, and scheduled scan preferences are stored locally on your Mac using UserDefaults. This data never leaves your device.

Notifications: If you enable scheduled scans, the app uses macOS User Notifications to alert you of network changes. Notification permission can be revoked at any time in System Settings › Notifications.
