If a single large network is divided into multiple subnets, the performance of the e

The subnet address and broadcast address are not given directly because the condition is given precedence. However, these two parameters require that we use the IP address and subnet mask to derive the subnet address and broadcast address. Ideas are as follows:1. The subnet

What is an IP addressThe so-called IP address is a 32bit address assigned to each host connected to the Internet. In accordance with the TCP/IP protocol, IPs are represented by binary, each IP address is 32bit long and bits are converted to bytes, which is 4 bytes. For example, a binary form of the IP address is "00001010000000000000000000000001", so long address, people are too laborious to deal with. In order to facilitate people's use, IP addresses are often written in decimal form, using sym

Technorati label: Subnet Mask, Network 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 subnet

There are two ways to compute the subnet mask: Method One: Use the subnet number to calculate: 1. First of all, the number of subnets from the decimal number into binary number; 2. Then, the number of digits of the binary number obtained by the statistic is set to n; 3. Finally, the subnet

The subnet mask is used to determine whether the IP addresses of any two computers belong to the same subnetwork. The simplest understanding is that after the IP address and subnet mask of the two computers perform the and operation, if the result is the same, the two computers are on the same sub-network and can comm

The Ip2long IP address is converted to an integer type.Long2ip integer data is converted to IP. The subnet mask is converted to a mask length mode:$slash _notation = strlen (Preg_replace ("/0/", "", Decbin (Ip2long ($subnet _mask)));$bits =strpos (Decbin (Ip2long ($mask)), "

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

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 Intranet are 218.102.142.7 and 218.102.142.219. Try to calculate the

IP address and subnet mask 1. IP Address:The Internet is formed by the interconnection of different physical networks. The computer communication between different networks must have a corresponding address ID, which is called an IP address. IP addresses provide a uniform address format consisting of 32 bits. Because the binary format is inconvenient to use, users can use the "dot-decimal" method. The IP ad

Subnet Mask and IP address operation subnet mask: function: divide an IP address into two parts: network address and host address. Once the subnet mask is set, the network address and host address are fixed. Calculation: Convert t

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
