Supported Formats

All these formats work:

netscan -l 00:50:56:C0:00:08   # Colons
netscan -l 00-50-56-C0-00-08   # Dashes
netscan -l 005056C00008        # No separators
netscan -l 00:50:56            # OUI only (first 3 bytes)

Batch Lookup

Look up multiple MACs from a file:

# Create file with one MAC per line
echo "00:50:56:C0:00:08
AC:DE:48:00:11:22
B8:27:EB:12:34:56" > macs.txt

# Batch lookup
netscan -b macs.txt -o results.json

Search by Vendor

# Find all Apple OUIs
netscan --vendor Apple

# Find Cisco entries
netscan --vendor "Cisco Systems"

JSON Output

netscan -l 00:50:56:C0:00:08 --json
