places, while the number of hosts is too small, therefore, the host addresses it provides become increasingly scarce. Currently, in addition to using NAT to allocate reserved addresses within an enterprise, a high-category IP address is usually further divided, to form multiple subnets, which can be used by different user groups. This is mainly to effectively use the IP address in the case of network segmentation. By taking the high part of the host number as the
First of all, our premise is the local area network, so we mentioned the modification more specifically, is to find the subnet mask and the default gateway for proper padding.
Here are two specific ways to do this:
Method One, we find any other networked computer on the same LAN, locate and double-click the local connected Internet Protocol (TCP/IP) entry, and populate the
Not much to say, directly on the code.

I recently reviewed some network knowledge and saw the subnet mask. The subnet mask is encountered in actual use and tests, but the calculation of the subnet mask involves binary conversion, it is troublesome. This time, I saw a s
method One:
First locate any other networked computer on the same LAN, and then double-click the Local Internet Protocol (TCP/IP) entry, and fill in the default gateway and subnet mask inside the computer.
Method Two:
1, find the same LAN other normal operation of the computer, click on the Win+r key combination, in the pop-up dialog box directly input cmd, and then click Enter;
2, came to the

Subnet Mask and network address
A valid broadcast address is the network address of the host plus the largest host number. The network address is obtained by bitwise AND the machine's IP address and subnet
/** * Get broadcast address * */public static String getbroadcastaddress (string subnet, string IP) {string[] ips = ip.split ("\ \."); string[] subnets = subnet.split ("\ \"); StringBuffer sb = new StringBuffer (), for (int i = 0; i Get the Java implementation of the broadcast address based on the IP address and subnet mask
If a unit has multiple networks distributed across different regions and there are not many hosts on each NETWORK, applying for multiple NETWORK IDs will not only waste IP addresses, in addition, the Unit will pay a large economic cost. In this case, multiple subnets can share a single website address to save IP addresses and money. Next we will introduce the process of using the subnet mask to achieve this

Business development often causes many organizations to face the following problem: the number of workstations is increasing, and it is becoming increasingly difficult to manage a single large network. If a single large network is divided into multiple subnets, the performance of the e
Subnet Mask and IP address operation subnet mask: function: divide an IP address into two parts: network address and host address. Once the subnet mask is set, the network address and host address are fixed. Calculation: Convert t
This example describes JS authentication IP, subnet mask, gateway, and Mac methods. Share to everyone for your reference. as follows:

The subnet address and broadcast address are not given directly because the condition is given precedence. However, these two parameters require that we use the IP address and subnet mask to derive the subnet address and broadcast address. Ideas are as follows:1. The subnet
represents the different hosts within the network segmentAttention:Private IP is an IP address that everyone can access for use in the intranet.Let's explain what a subnet mask is, why put this concept with an IP address? Remember that because the subnet mask and IP are present together .The standard
There are two ways to compute the subnet mask:
Method One: Use the subnet number to calculate:
1. First of all, the number of subnets from the decimal number into binary number;
2. Then, the number of digits of the binary number obtained by the statistic is set to n;
3. Finally, the subnet
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
Many people are certainly not familiar with the subnet mask setting, which is a headache. Now I will tell you how to easily calculate the subnet mask and help people who like to be lazy :)
Everyone should know how many hosts are between the power 0 and the power 10 of 2? Let us also say that they are:1 2 4 8 16 32 6
Nowadays, the Internet is playing an increasingly important role in our daily lives and work. It can be said that without the Internet, we will not be able to work and live normally. As a programmer, most of the programs we write will also be related to the network. To use the network, you must first set the network configuration of the machine. The manual setting method is obviously not desirable, so we need to let the program complete it for us. The following is a very common Demo of C # setti
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
