weird ip address fe80

In Linux, IP addresses are classified into "Dynamic IP" and "static IP". Dynamic IP addresses are automatically cleared when the machine restarts, while static IP addresses are always bound. Static IP settings:Create a file ifcf

An IP address, but too much knowledge is associated with it Binary and 8 bits The number shown in the computer is 10, each key of the keyboard is encoded by a 8-bit binary, so 1 bytes equals 8 bits. For numbers, the binary of 1 is 00000001, 255 is 11111111, and the 256 binary is 9 bits. So from the 8-bit concept, 255 is the maximum value. But don't forget the number 0, from the 0~255, the total is 256, 2 of

the second group of numbers. In the above example, 108; Y is the third group of numbers, 22 in the above example; Z is the fourth group of numbers, 5 in the above example. There is also an interesting phenomenon. In the above formula, add N? 256 ^ 4, that is, IP = N * 256 ^ 4 + V * 2563 + X * 256 ^ 2 + Y * 256 + Z * 256 ^ 0 although the calculation result is different, however, it works the same and can be connected to the same website.

there are more weird variants. An IP address can be expressed in a mix of decimal, octal, and hexadecimal values, which is equally valid. For example, 204.71.200.68 can be expressed as 0xcc. 71.0310.0x44, can be further deformed as http://www.myyahoo.net @ 0xcc. 71.0310.0x44 because the content between http: // and @ has no function or meaning except disguise, u
