IP address and subnet mask

IP address and subnet mask 1. IP Address:The Internet is formed by the interconnection of different physical networks. The computer communication between different networks must have a corresponding address ID, which is called an IP address. IP addresses provide a uniform address format consisting of 32 bits. Because the binary format is inconvenient to use, users can use the "dot-decimal" method. The IP address uniquely identifies the number of the n

Examples of how to calculate subnet masks, network addresses, broadcast addresses, etc.

IP address is composed of network address + host address so you can get the network bit + host bit = 32 bitsThe concept of the same network segment :The same network segment refers to the IP address and subnet mask, and the same net address is obtained.Want to be in the same network segment, must do network identity is the same, that is, network address. For example, Class A address: Only the first paragraph (255.0.0.0); Class B Address: First to seco

Windows Azure Virtual Machine (30) modifies the subnet of an Azure VM

Windows Azure Platform Family of articles Catalog  When I use Azure virtual machine VMS, I often use them in conjunction with the virtual network.But sometimes, we deploy in the virtual network subnet subnet information is wrong, I want to modify this virtual machine belongs to the subnet, how should I modify?Let me briefly introduce you here.  1. First, we have

Reprinted: determines whether the subnet mask is in the same network segment.

We can determine whether the IP address is in the same CIDR Block through the IP address directly. The following describes how the computer uses the subnet mask to determine whether the IP addresses of two hosts are in the same CIDR block ~ How can I calculate the network ID if I want to have the same network ID in the same network segment? Network Identification Algorithms for various IP addresses are differ

Remember that because the subnet mask and IP are present together .The standard subnet mask for Class A is 255.0.0.0The standard

How to discover subnet masks and default gateways

In project implementation and network device debugging, we often need to find the subnet mask and default gateway of the device so as to correctly configure devices such as routers, switches, and firewalls.

Two examples of subnet division

Example 1: In this example, the number of subnets is used to divide subnets without considering the number of hosts. A group company has 12 subsidiaries and each subsidiary has 4 Departments. The superior provides a CIDR block of 172.16.0.0/16 for each subsidiary and its departments to allocate CIDR blocks. Idea: Since there are 12 subsidiaries, We need to divide them into 12 sub-network segments, but each subsidiary has 4 Departments, therefore, it is necessary to divide the CIDR blocks of each

Huawei oj--determine whether two IPs belong to the same subnet

Title DescriptionA subnet mask is a basis for determining whether the IP addresses of any two computers belong to the same subnet.The subnet mask is the same as the IP address structure, which is a 32-bit binary number, where the network number section is all "1" and the host number is all "0". Use the subnet mask to determine whether two hosts are in the same

Javascript logic judgment for IP addresses, subnet masks, and gateways _ javascript skills

This article mainly introduces the logic judgment of js for IP addresses, subnet masks, and gateways. If you are interested, refer to the js verification for static address configuration, I found a lot of information about ip addresses and masks on the Internet. I didn't have ip addresses, submask, or gateway logic judgments. I wrote my own code for reference. Common knowledge about Gateway addresses: First:And calculate 1 and 1, and 0 are 0, 0 and 0
