what is subnet mask in networking

Non-symmetric network failure is caused by subnet mask faultsNetwork connectivity is a common phenomenon. I believe many people will focus on Network cables, Nic drivers, and nic parameters. When checking Nic parameters, they may also focus on key parameters such as IP addresses, Gateway Addresses, DNS servers, and DHC

calculated as follows: 2017.hangzhou.hangzhou.00000001, which is converted to a 10-digit system, that is, 0.0.0.1,0.0.0.1 indicates the host ID. To be in the same network segment, you must have the same network ID.Let's take a look at the Class B IP address changed to the default subnet mask.For example, IP Address: 188.188.0.111, 188.188.5.222, all

networks.4. Class DClass D addresses start at 111 0. This represents a eight-bit group from 2 2 4 ~ 2 3 9. These addresses are not used for standard I P addresses.Instead, a Class D address refers to a set of hosts that are registered as members of the multicast team. Multicast teams and emailThe allocation list is similar. Just as you can use the Assign list to publish a message to some people, you canMulticast addresses send data to some hosts. Mul

PS: What is the difference between the mask and the channel? Here we can use the concept of the mask to help understand the meaning of the channel, the usual masking can be seen as this: when you select a portion of the image on the PS image using the selection tool, the gray-black part of the selection

In image processing, the word mask is often encountered. So what does this word mean? Here's a quick explanation. 1. What is masking First of all, we look at what is the process of
