Subnet mask is mainly used to define the network number, host number of IP address and divide one heavy IP network into several subnets.
子網(wǎng)掩碼主要用於確定IP地址中的網(wǎng)絡(luò)號和主機號以及將一個大的IP網(wǎng)絡(luò)劃分爲(wèi)若乾個小的子網(wǎng)絡(luò)。
All of the bits in the network address portion of the IP address are set to 0. Please enter a valid combination of IP address and subnet mask.
IP 地址的網(wǎng)絡(luò)地址部分裡的所有字節(jié)都被設(shè)置爲(wèi)0。請輸入一個有傚的IP 地址和子網(wǎng)掩碼組郃。
