MAC address (Media Access Control address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.

Our MAC address lookup tool utilizes a vast database of MAC addresses and vendor names. When you enter a MAC address, our tool searches for it in the database and provides you with the associated vendor name. Similarly, by entering the vendor name, you can find all the MAC addresses associated with that vendor.

2.1 Factoring: a 2-9b 2 Theory : A difference of two perfect squares, A 2 - B 2 can be factored into (A+B) • (A-B) Proof : (A+B) • (A-B) = A 2 - AB + BA - B 2 = A 2 - AB + AB - B 2 = A 2 - B 2 Note : AB = BA is the commutative property of multiplication.

Use our MAC Address Lookup tool to find detailed information about any MAC address instantly. You can use this information in countless ways: Quickly determine the manufacturer and model of a device based on its MAC address. Enhance security by verifying unfamiliar devices before allowing them on your network.

For a manufacturer search using a MAC address, at least the first 6 characters (24 bits or 3 bytes) of your MAC address are required. If also the smallest address ranges assigned by the IEEE are to be searched, the first 20 characters (80 bits) of your MAC address are required. You can enter your MAC address with or without separator ("-" or ":").

2018年11月10日 · mac地址由IEEE组织统一管理，所有合法的mac地址都可以通过IEEE官网查询到厂商。 下面列出思科厂商截至到2018年11月10日所有的的地址前缀。 共计841个前缀。 国内HuaW*只有478个，H2+1C只有27个。 国内两个厂商加起来才只有思科的一半多，从MAC地址前缀就应该看出CISCO有多么牛逼了。 帖子的最底部给出IEEE公布的MAC地址链接，里面有所有的MAC地址前缀分配情况。 IEEE组织会定期更新oui文件，用于查询mac地址厂商。 IEEE的链 …
