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
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) entr

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
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
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 ~

It is called loopback address ). No matter what program, once data is sent using the return address, the protocol software returns immediately without any network transmission.According to TCP/IP protocol, 1.

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
International regulations: divide all IP addresses into A, B, C, D, and E. Class
DefaultSubnet Mask: Class A is 255.0.0.0; Class B is 255.255.0.0; Class C is 255.255.255.255.0. The subnet mask is a 32-bit address. It is used to shield a part of the IP address to distinguish
What are IP addresses, subnet masks, routes, and gateways? Often friends ask me, indeed these terms are often seen by us, today to the people to talk about the meaning of these terms:1.IP Address:The IP address has a 32-bit connection address, consisting of 4 8-bit fields, a 8-bit field called a 8-bit group, and each 8
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

Only in this way can you determine the actual size of the network.If you wantSend it to all devices in the subnet (for example, group broadcast) and send it to the broadcast address. In the later part of this article, I will show you a simple way to eas
Question:
If a company has 100 computers and a class C registered IP address segment: 218.102.142.0, its Intranet (LAN) needs to be further divided into two subnets, each with 40 computers and 60 computers,
Requirements:
(1) Specify the subnet mask;
(2) assume that the IP addresses of one or two computers in the
The IP address consists of 32 bits, divided into four segments, consisting of a network number and a host number. Also divided into a b C D e Five address, where a B class C address for distribution to the global network users, D E class is a special address.1, Class A address 1.0.0.0 to 126.255.255.255Only the first paragraph is the network number, and the remaining three paragraphs are the host number. In binary notation, there are 8 bits, or one by
