broadcast address, not the host address.C. each bit of the host ID cannot be "0". If each bit is "0", it means "only this network", and there is no host on this network. Concept and function of subnet mask The subnet mask is a 32-bit binary value applied to TCP/IP networks. It can block part of an IP

How to determine whether two IP addresses are in the same CIDR Block? To determine whether two IP addresses are in the same CIDR Block, perform and calculate the IP addresses and subnet masks respectively. The result 1 is displayed, if the network numbers are the same, they

An account is bound to a computer. My computer does not have a network. Can I use another person's network ???

1) Basic Idea: Determine whether two IP addresses are in the same CIDR block, and separate the IP addresses with the subnet mask. The result is the network number. If the network number is the same, it is in the same subnet. Otherwise, it is not in the same subnet. 2) Implementation: *** [isEqualIPAddres 1) Basic Idea: Determine whether two
