|127.0.0.1/24. 24 indicates that the first 24 bits in the subnet mask are used as effective bits, for example, 32-24=8 bits are used to express host numbers. In this way, the subnet can accommodate 2 ^ 8-2 = 254 hosts. And 127.0.0.1/24 indicates the IP network segment scope of 127.0.0.1~127.0.0.255.|
