The unique MAC address helps you a little in identifying which device is which. This is useful for connecting to other devices which are supposed to be locked to specific other devices (cable modems). Some devices allow you to change the MAC address advertised in software, for instance Ethernet adapters or wifi adapters. MAC addresses are generally unique to a device, but some manufacturers re-use MAC addresses within a particular model or part number. Dell has a range of MAC addresses that it uses, and Apple has another. There are several lookup tools on the web, such as or. This is called the OUI (organizationally unique identifier). Please enter MAC addresses as 6 octets (without punctuation or separated by colons or dashes).MAC addresses can sometimes be used to identify the maker and potentially model of the device even without the device in hand.

You can use the lookup below to identify vendors. This is particularly helpful, for example when using the Bind IP to MAC function of most of our routers, whereby you can assign/register known devices (and exclude unknown ones).įortunately, within every MAC address the first two octets are (supposed to) identify the vendor. For example, if you are trying to distinguish between an iPhone, a Samsung Phone and a Toshiba TV, knowing the vendor from the MAC address will make that easy. Often, knowing the vendor (manufacturer) will make it a lot easier. Sometimes a device will appear in an ARP table or some other log on your router or switch and you don't immediately recognise it. It's fixed to the hardware (at OSI Layer 2) as opposed to the IP address which is variable and is at the TCP/IP layer. The MAC address is the unique hardware address of any Ethernet or WiFi device.
