how to calculate subnet and host

We know that the IP address is a 4-byte (total 32bit) number, divided into 4 segments, 8 bits per segment, and periods separated by a period. For ease of expression and recognition, the IP address is expressed in decimal form such as 210.52.207.2, each paragraph can represent the maximum number of decimal not more than 255. The IP address consists of two parts, the network number (Netgwork ID) and the host ID. The network number identifies a

This article mainly introduces how to use Python to calculate network segments based on IP addresses and subnet masks. It involves Python character string operation techniques based on the Linux platform and has some reference value, for more information about how to use Python to calculate network segments based on IP addresses and

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,

Not much to say, directly on the code.

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 201710000224.0 11111111 11111111 11100000 00000000 Network Address: Calculate the IP addr

A few words to master subnet mask, IP address, host number, network number, network address, broadcast address1, 191.172.16.10.33/27 in the/27 that is, the subnet mask is 255.255.255.224 that is 27 full 12. From the subnet mask 255.255.255.252 to obtain its network bit is 30 bits, so only the remaining 2-bit master, th

Linux generally uses the ifconfig command to modify the IP, gateway, or subnet mask of a Linux host. 1. Command format:ifconfig [Network Devices] [parameters]2. Command function:The Ifconfig command is used to view and configure network devices. This command can be used to configure the network appropriately when the network environment changes. 3. Command parameters:up starts the specified network device/N
