1) Basic Idea: Determine whether two IP addresses are in the same CIDR block, and separate the IP addresses with the subnet mask. The result is the network number. If the network number is the same, it is in the same subnet. Otherwise, it is not in the same

Find the start and end IP addresses of a CIDR block Find the start and end IP addresses of a CIDR blockFor example, for a network segment (192168.1.5/24), its subnet mask is divided:11111111.11111111.11111111.00000000 (255.255.255.0)Note: If the

very difficult. Once the IP address of the default gateway must be modified due to migration or other reasons, this will cause a lot of trouble to the network management, so it is not recommended.In Windows 9x, you can set the Default Gateway by right-clicking "Network neighbors" and clicking "properties" in the pop-up menu ", in the network Properties dialog box, select "TCP/IP protocol" and click "proper

Php is used to obtain the start and end IP addresses of a CIDR block. This example describes how to obtain the start and end IP addresses of a network segment in php. Share it with you for your reference. The details are as follows: For example, for a network segment (192168.1.5/24), its subnet mask is divided:11111111

As we all know, IP is made up of four numbers, here, let's first look at the Class 3 commonly used IPClass A IP segment 0.0.0.0 to 127.255.255.255Class B IP segment 128.0.0.0 to 191.255.255.255Class C IP segment 192.0.0.0 to 223.255.255.255　　The default subnet mask assigned

the network size. Its addressing scheme uses the concept of "class. The definitions of IP addresses A, B, and C are easy to understand and divide. However, in actual network planning, they are not conducive to effectively allocating limited address space. For Class A and Class B addresses, few companies can use such A large scale, and the number of hosts for Class C addresses is relatively small. Therefore, a type of

needs to adjust the size of the sub-network.Note: In this way the subnet is divided into subnets, all 0 subnets, and all 1 subnets are available.CIDR (No-class inter-Domain routing protocol):The non-class inter-domain routing protocol allows multiple classes to be merged into a larger network, called a hyper-net.For example, the 192.24,8.0~192.24.15.0 these 8 have a class network, you can synthesize a network number of 192.24.8.0, the
