What is a MAC Address?
A MAC (Media Access Control) address is a unique identifier assigned to a network device. It helps devices communicate with each other on a local network. Every network interface card (NIC) in a device, such as Wi-Fi or Ethernet, has its own MAC address.
MAC addresses usually use the same 48-bit value, but different systems display that value in different formats. The main difference comes from the separator style.
| Format | Example | Common Use |
|---|---|---|
| Colon-separated | AA:BB:CC:DD:EE:FF | Linux, macOS, networking tools |
| Hyphen-separated | AA-BB-CC-DD-EE-FF | Windows |
| Dot-separated | AABB.CCDD.EEFF | Cisco IOS and some network devices |
| Plain / No separator | AABBCCDDEEFF | Programming, APIs, databases |
Frequently Asked Questions (FAQs)
What is OUI or Vendor Number in MAC Address?
A MAC OUI (Organizationally Unique Identifier) is the first six hexadecimal digits of a MAC address. It identifies the company or organization that received the MAC address block. MAC OUI number is also called a vendor number. You can use this number to lookup and identify the registered vendor.
What is MAC Serial Number?
The MAC serial number is the last six hexadecimal digits of a MAC address. The manufacturer uses this part to give each device a unique MAC address within its assigned block.
What is Reverse MAC Lookup?
Reverse MAC address lookup lets you search by a vendor name instead of a MAC address. You can do a reverse lookup using our MAC address vendor lookup tool by entering the vendor name. It shows the MAC address blocks and OUI that are registered to that company.
Can I Identify a Device by MAC Address Online?
Partially, yes. A MAC address lookup can reveal the device manufacturer (vendor name), such as Intel or Apple. But it cannot tell you the exact device model or the device owner. To identify the exact device, check your router’s connected-device list.
Can I Change the MAC Address of My Device?
Not permanently, but many devices let you change or randomize the MAC address through software settings. Temporary changes are carried out during device network testing. However, the original hardware MAC address does not change.
Can a Device have Multiple MAC Addresses?
Yes. A device can have more than one MAC address if it has multiple network interfaces, such as Wi-Fi, Ethernet, or Bluetooth.
Are a MAC address and an IP address the same?
No. A MAC address identifies a network device, while an IP address identifies the device’s location on a network. They serve different purposes.
