into two levels: network address and host address, while the latter is divided into multiple levels. The subnet mask can only be divided at two levels, resulting in the same IP address: 67.101.121.131. Its subnet mask may be 255.0.0.0 or 255.255.0.0, it may also be another value. Therefore, when a given IP address, es

find that the subnet mask is the same for dividing 4 subnets, 5 subnets and 6 subnets, and the same as the subnet mask, is it wrong? Should the three subnet masks be different? Well, this is the case. Because the binary values of
number of hosts identified by the six subnets will be less than 254. Please note that!
Q:1. you may have such questions. For example, in the above example, the binary value of 6 is 110, so why do we need to set the positions corresponding to the first n digits of the host number in the subnet mask to 1, instead of replacing the first n digits with the binary 110 of 6?The answer is: What is the purpose of t
.
Well, this question is very good, the answer is this: we calculate the subnet mask what is the purpose. is to be able to parse out the network number when doing ' and '. That is to say, the location of the network number should be 1 (including, of course, the location corresponding to the subnet number), then obviously, you write 110 is not correct, if you wri
number can be resolved, that is, it and the network number corresponds to the location should be 1 (of course, including the sub-network number corresponding to the location), then it is obvious that you write 110 is not right, if you write so, then it is the first two of the host number as the subnet number, So this will be divided by up to 2 subnets (not sure, there is a way to calculate the number of subnets below), and we originally wanted to div
do we need to set the positions corresponding to the first n digits of the host number in the subnet mask to 1, instead of replacing the first n digits with the binary 110 of 6? The answer is: What is the purpose of the subnet mask calculation? It is hoped that it will be able to parse the network number when doing "a
Python: a simple method for converting the subnet mask and a python Subnet Mask
This article describes how to convert the subnet mask in Python. We will share this with you for your reference. The details are as follows:

The subnet mask cannot exist alone, it must be used in conjunction with an IP address. The subnet mask has only one function, which is to divide an IP address into two parts: network address and host address.The subnet mask settin
As for subnet division, the subnet mask is odd. 1.0.1.0 -- 1.0.3.255 Fujian Telecom converts the subnet mask to an IP segment 1.0.1.0/24--1.0.2.0/23, if two IP addresses are replaced by binary IP addresses in a general way, or the budget is 0001.00000000.00000001.00, the
The network does not pass, this is the most network problem table image, but if you can access me, but I can not access you, this problem is more troublesome. This article is the author in the actual combat in a subnet mask caused by the fault summary.

that the above table points out the number of hosts and the number of available hosts two items, which is why. Because when all host bits of an address are "0", this address is the network address of the subnet, and is the broadcast address when all host bits are "1". We can also use a variable-length mask (VLSM), which means that a network can be configured with a different
the following 2 format representation methods:
1. By dotted decimal notation with the same IP address format
such as: 255.0.0.0 or 255.255.255.128
2. After the IP address plus the "/" symbol and 1-32 of the number, where 1-32 of the number represents the subnet mask in the length of the network identification bit
For example: 192.168.1.1/24 subnet
. A power number of 2. We should be proficient in the 28 (256) within 2 of the power representation of the decimal number (such as 128=2^7, 64=2^6, etc.), so that we can immediately calculate the number of Subnet_block and Ip_block.Iii. Illustrative examplesNow, by doing some practical examples, you can have a deep understanding of the decimal algorithm of the subnet mask and host block.1. We know the numbe
Windows to bring a calculator on the line.) Open Calculator, point to view > scientific type, enter decimal number, then click "Binary" This single point, you can switch to binary. )Switch the netmask to binary, and we'll find that all the subnet masks are made up of a string of [red] continuous [/red] 1 and a string of [red] continuous [/red] 0 (altogether 4 segments, 8 bits per segment, total 32 digits).

After the address is changed, the network of Company A can access the server of the company immediately.
