In today's digital world, network security is a top priority for businesses and individuals alike. One essential aspect of network security is identifying devices connected to your network. This article provides a comprehensive guide on how to find the Media Access Control (MAC) address of devices connected to a Synology Network Attached Storage (NAS) system.
What is a MAC Address?
A MAC address is a unique identifier assigned to every device connected to a network. It is a 12-digit hexadecimal number, often represented in groups of two digits separated by colons or hyphens. MAC addresses are used by network devices to communicate with each other and help in network security by allowing administrators to identify and manage devices on their network.
Finding MAC Addresses on Synology NAS
Synology NAS provides several methods to find the MAC addresses of devices connected to the network. In this guide, we will explore three methods:
Method 1: DSM Finder
DSM Finder is a built-in utility in Synology DiskStation Manager (DSM) that allows you to search for devices on your network and view their MAC addresses. Here's how to use it:
- Log in to your Synology NAS web interface.
- Navigate to Control Panel > Network > Network Interface.
- Click on the "DSM Finder" tab.
- Click the "Scan" button to search for devices on your network.
- Once the scan is complete, locate the device you are looking for in the list and note down its MAC address.
Method 2: Command Line Interface (CLI)
You can also use the Synology NAS Command Line Interface (CLI) to find MAC addresses. Here's how:
# Log in to the Synology NAS CLI
ssh root@
# Type the following command to display a list of connected devices and their MAC addresses
netstat -anp tcp | grep ESTABLISHED | grep -vE '127\|0.0.0.0\|::1' | awk '{print $7}' | awk -F: '{print $1}'
Method 3: Synology Surveillance Station
If you have Synology Surveillance Station installed on your NAS, you can use it to find MAC addresses of devices connected to your network cameras. Here's how:
- Log in to your Synology Surveillance Station web interface.
- Navigate to the "Live View" tab.
- Select the camera you want to check and click the "Device" tab.
- Locate the "Network Information" section and note down the MAC address.
Finding MAC addresses on a Synology NAS is a straightforward process that can be accomplished using various methods, including DSM Finder, Command Line Interface, and Synology Surveillance Station. Understanding how to find MAC addresses is essential for network security and device management.
