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 by XP is only 255 or 0 per segmentClass A default subnet
You must know something about the IP address, right? We know that the TCP/IP protocol that is widely used in the Internet is to differentiate between different hosts by using IPs. If you've ever had a TCP/IP protocol set up, then you're bound to encounter the term subnet mask (Subnet mask), so do you know what a
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 DHCP servers. In fact, there is also a network parameter-

The IP address is the network number and host number to represent the host on the network, only in a network number under the computer can be "direct" interoperability, different network number of the computer through the gateway to exchange. But such a division does not seem very flexible in some cases. For this reason, the IP network is also allowed to be partitioned into smaller networks called subnet
disadvantages of ipv4 have gradually been exposed, that is, the network number occupies too many places, and the number of hosts is too small, so the host addresses it provides become increasingly scarce, currently, in addition to using the reserved IP address to allocate nat addresses within an enterprise, a high-class IP address is usually divided to form multiple subnets for use by different user groups.This is mainly to effectively use the IP address in the case of network segmentation.

First of all, we look at a CCNA test common problem: The IP address of a host is 202.112.14.137, the mask is 255.255.255.224, requires computing the network address and broadcast address of the host network. 255.255.255.224 masks contain 256-224 = 32 IP addresses (including network address and broadcast address), the network address with this ma

All steps are far from the most primitive binary way, the direct hit principle, please read carefully.1. Logic algorithmLogic and operations and logic or operations are used when computing network bits, host addresses, broadcast addresses, so it is necessary to understand their algo

Here, let's take a look at three common IP addresses.Class a ip segments 0.0.0.0 to 127.255.255.255Class B IP segments 128.0.0.0 to 191.255.255.255C-type IP segments 192.0.0.0 to 223.255.255.255The default subnet mask allocated by XP is only 255 or 0 for each segment.Class A default subnet

Subnet Mask is the basic knowledge that each network administrator must master. Only by mastering it can you truly understand the TCP/IP protocol settings. The following describes what a subnet mask is.

are suitable for small networks such as campus networks, and each class C network can have up to 254 hosts.
From the above introduction we know that the IP address is the network number and host number to indicate the host on the network, only in a network number under the computer can be "directly" interoperability,
computers with different network numbers need to be connected through gateways. But such a division appears and is very inflexible in some cases. For this reason, the IP network
Subnet mask (subnet mask) definitionIt is a bitmask that indicates which bits of an IP address identify the subnet on which the host resides and which bits identify the host. The subnet mask
IP address Structure
To understand what a subnet mask is, you must understand the composition of IP addresses. The Internet is composed of many small networks, each of which has many hosts, thus forming a hierarchical structure. When designing an IP address, considering the hierarchical features of Address Allocation, each IP address is divided into two parts: the network number and the host number to faci
In order to learn more about the TCP/IP protocol, I have read a lot of relevant information recently and collected the following records for later use and convenience:

001. Q: What is the difference between IP address, subnet mask
The most direct role of the subnet mask is to determine whether the IP address is within the same network segment as another IP address.
Here is a simple look at the basic configuration of IP on a computer

Subnet Mask: 255.255.255.0
Default gateway: 192.168.0.1
