Subnet Mask and IP address calculation network address and broadcast address conversion
IP Address: 202.112.14.20.Subnet Mask: Too Many Subnet MaskWhat is the network address and broadcast address of this host?Solution:Step 1: Determine the
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 cannot exist alone, it must be used in conjunction with an IP address. The subnet ma
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
IP Address: 192.168.0.5
Subnet Mask: 255.255.255.0
Default gateway: 192.168.0.1
Example above, IP address, subnet
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

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 ad
represents the different hosts within the network segmentAttention:Private IP is an IP address that everyone can access for use in the intranet.Let's explain what a subnet mask is, why put this concept with an IP address? Remember that because the subnet mask and IP are present together .The standard subnet mask for C
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 s
TCP/IP Note 2. Network Layer (1) -- IP, subnet, CIDR1. IP1.1 supporting agreementIP is one of the two most important protocols in the TCP/IP system.There are also four protocols used in combination with the IP protocol:(1) ARP (Address Resolution Protocol) Address Resolution Protocol(2) RARP (Reverse Address Resolution Protocol) Reverse Address Resolution Protocol(3) ICMP (Internet Control Message Protocol)
It is known that a network is required to be divided into subnets of the same size.For example, a known NETWORK:192.168.0.0/23 subnet, which lists all the subnet network addresses according to the subnet block B size to be divided
Full solution D-LINK Switch configuration in the enterprise network VLAN subnet usage, on the D-LINK Switch configuration problems, from the following aspects: from the enterprise network plan four VLAN subnet classification and structure, DES-3326SR Switch configuration process is introduced. The example below gives a
Set the network backbone and the layer-3 Switch required to connect to the subnet. Let's talk about how to set the layer-3 switch. The following three-tier switch settings are indispensable for the network backbone, and the three-tier switch settings for the connection subnet are explained by professionals to ensure yo
