PrefaceThis document is simply a logical algorithm, and how to compute network bits, host bits, and broadcast addresses in the case of known IP addresses and subnet masks. All steps are far from the most primitive binary way, the direct hit principle, please read carefully.1. Logic algorithmLogic and operations and logic or operations are used when computing network bits, host addresses, broadcast addresses

I don't need to analyze it professionally. I use dummies to answer questions. This is a simulated question. Use this question as an example. URL type: Of course, it is Class B. Convert the IP address and subnet mask to binary, and then perform operations on them. 145.189.24.3 10010001 10111101 00011000 00000011

The IP address is composed of four digits. Here, let's take a look at three common IP addresses.Class a ip segments 0.0.0.0 to 127.255.255.255Class B IP segments 128.0.0.0 to 191.255.255.255C-type IP segments 192.0.0.0 to 223.255.

Network Segment Encyclopedia business cards A cidr Block refers to the part in a computer network that uses the same physical layer device (transport medium, repeater, hub, and so on) for direct communication. From one IP address to another, it is like a network segment from 192.168.0.1 to 192.168.255.255. Network Segment The subnet
