192.168.0.1/16,1/24;192.168.1.1/16,1/24 the meaning of the IP segment

First, let's look at the conversion knowledge of the binary:

Binary number converted to decimal number binary 1101 converted to decimal
1101 (2) =1*2^0+0*2^1+1*2^2+1*2^3=1+0+4+8=13
Converted to decimal to the right-to-left with the binary of each number to be multiplied by 2 of the corresponding sub-square
But the second is going to start at 0.
Instead, divide the decimal 13 by 2, and each of the remainder is recorded next to it.
Finally, the remainder is ranked from the bottom up to get 1101
Decimal Turn binary:
Divide by 2 to the result of 1
To write the remainder and the last 1 backwards from the bottom up is the result.
For example 302
302/2 = 151 more than 0
151/2 = 75 more than 1
75/2 = 37 more than 1
37/2 = 18 more than 1
18/2 = 9 more than 0
9/2 = 4 more than 1
4/2 = 2 more than 0
2/2 = 1 more than 0
1/2 = 0 More than 1
So the binary is 100101110

Let's understand the general [object Object] expression [object Object] formula:
 
[object Object] [object Object] area [object Object] network [object Object] [object Object] [object Object] [object Object] [object Object] [object Object] netmask: 0-255 A total of 256 binary representation of [object Object] 11111111 of 8 [object Object] 1
[object Object] net [object Object] [object Object] [object Object] The four sections are 255.255.255.255 = 11111111.11111111.11111111.11111111111 = 32 [object Object] 1
 
Class C 255.255.255.0 = 11111111.11111111.11111111.00000000 = 24 [object Object] 1
Class B 255.255.0.0 = 11111111.11111111.00000000.00000000 = 16 [object Object] 1
Class A 255.0.0.0 = 11111111.00000000.00000000.00000000 = 8 [object Object] 1
 
[object Object] To write the switch policy [object Object] [object Object] use [object Object] [object Object] [object Object]: inverted mask
255.255.255.0 = 0.0.0.255
255.255.0.0 = 0.0.255.255
255.255.255.0 = 0.255.255.255

192.168.0.1/16, 1/24 192.168.1.1/16, 1/24

The number of digits of the subnet mask. The subnet mask is calculated by 32 bits, and the number of writes is 1, and the other digits are all 0 .

192.168.0.1/16;192.168.1.1/16 that corresponds to 11111111 11111111 00000000 00000000 converted to decimal is 255.255.0.0 is also the IP 192.168 fixed

192.168.0.1/24;192.168.1.1/24 is for 11111111 11111111 11111111 000000000 Convert to Decimal is 255.255.255.0 is also the IP 192.168.0/1 fixed

192.168.0.0/24 means that the network code occupies 24 bits, that is, the network can have 254 host (2^8-2) IP range: 192.168.0.1~192.168.0.254 192.168.0.255 is the broadcast address, can not be used by the host. When setting the IP address: 192.168.0.x subnet Mask: 255.255.255.0 192.168.0.0/16 indicates that the network code occupies 16 bits, which means that there can be 65,534 host (2^16-2) IP range on the network: 192.168.0.1~ 192.168.255.254 192.168.255.255 is a broadcast address and cannot be used by a host. When setting the IP address: 192.168.x.y Subnet Mask: 255.255.0.0
