The simplest understanding is that the respective IP addresses of the two computers and the

This article describes in detail how to configure network IP addresses. What operations do we need? I believe that reading this article will help you.
A few days ago, the netizen harcsbg encountered a strange subnet mask problem during network IP address configuration. harcsbg asked for help in the ccid it community.
Dear experts, I have encountered a strange problem in network IP address configuration toda
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
1. Use the number of subnets for Calculation
Before obtaining the subnet mask, you must first understand the number of subnets to be divided and the number of hosts required in each subnet.
1) convert the number of subnets to binary representation.2) The number of digits to obtain the binary value is N.3) obtain the subnet
Because to do the static address configuration JS Check, find a lot of information found on the internet is about ip,mask validity check, no ip,submask,gateway logic judgment, write down the code for the needs of people reference.Popularization of Gateway address knowledge:is to proceed with the operation 1 with 1 with a 0 for 0,0 and 0 for 0. First, the IP and subnet masks are expanded 10.70.64.223

The IP address consists of 32 bits, divided into four segments, consisting of a network number and a host number. Also divided into a b C D e Five address, where a B class C address for distribution to the global network users, D E class is a special address.1, Class A address 1.0.0.0 to 126.255.255.255Only the first paragraph is the network number, and the remaining three paragraphs are the host number. In binary notation, there are 8 bits, or one byte is the network number, and 24 bits, or thr

1. How many subnets will be generated
The X power of 2-2 (X represents the mask bit, that is, the part of the binary system that is 1. In the current network,-2 is no longer required and can be used in all, however, you need to add the corresponding configuration commands. For example, you can use all the commands by adding the IP subnet zero command to the Cisco router .)
Note: I have read a lot of boo
Have always felt that the internet is a magical thing, in the use of the time is also very confusing, you think?Have you ever wondered: what does a subnet mask do? Why is it as if it can be configured to surf the Internet (of course, now sometimes it seems to be a spell of luck)?Pre-Knowledge:

1. The subnet mask is the IP reference:Split the network segment with!Like 192.168.0.1 and 192.168.0.2.(1). Subnet mask is 255.255.255.0So 192.168.0.X in the same network segment, can access each other.(2). Hope the Mask is 255.255.0.0So 192.168.x.x in the same network segme
