mac地址克隆 破解共享限制让多机上网（MAC address, clone, crack, sharing restrictions, allowing multiple machines to access the Internet） MAC address, clone, crack, sharing restrictions, allowing multiple machines to access the Internet In many places, ISP will limit the number of users to share the Internet via the MAC function, that is, to record the MAC address of a computer in your lan. What is the MAC address? And how to deal with MAC Internet restrictions? First, understand the MAC address Network devices (including all kinds of wired wireless cards, broadband MODEM, broadband routers, etc.) have two types of addresses in use, one is the IP address, and the other is the MAC address. MAC (Media, Access, Control, media access control) address, that is, the physical address of the network device, is the identification of the LAN (LAN) computer. Its length is 48 bits, 16 hexadecimal numbers composed of 12 00~0FFH, between each 16 hexadecimal number , separated, such as a piece of network equipment MAC address is 08:00:20:0A:8D:6E, of which the first 6 hexadecimal number 16 08:00:20 represents the network hardware manufacturers number, which is composed of IEEE (Institute of electrical and electronic engineer) distribution, and then 3 hexadecimal number 16 0A:8D:6E represents a network product manufactured by the manufacturer (such as card number). The IP address and the MAC address are represented in binary in the computer, the IP address is 32 bits, and the MAC address is 48 bits. IEEE Ethernet address, divided into several independent groups. Continuous production, the Ethernet network equipment manufacturers will buy one group, the specific production, the physical address is usually burned into the card from the card manufacturer EPROM (a flash chip, usually through the program, in order to wipe the writing) as identity card. In the data transmission of identification data issued by the computer and receiving data of host address. It is precisely because of the MAC address, jus
