Subnet division and summary
2022-07-01 17:56:00 【It's a cinch!】
Subnet partition :
Divide a network segment into several different network segments , Allocate according to the actual environment ( Reduce IP Address )
eg.4 Machine room , Each machine room needs 60 individual IP Address .C Class segment : 200.1.1.0 255.255.255.0
1100 1000.0000 0001.0000 0001.XX00 0000
1111 1111 . 1111 1111 .1111 1111 . 1100 0000 Subnet mask
200.1.1.0 /26(26: The subnet mask has 26 A network bit )
1100 1000.0000 0001.0000 0001.0000 0000 - 200.1.1.0 255.255.255.192
Range :200.1.1.1 - 200.1.1.30 (30: You can use IP - 1)
1100 1000.0000 0001.0000 0001.0100 0000 - 200.1.1.64 255.255.255.192
Range :200.1.1.65 - 200.1.1.94 (94: 64 + 30)
1100 1000.0000 0001.0000 0001.1000 0000 - 200.1.1.128 255.255.255.192
Range :200.1.1.129 - 200.1.1.158
1100 1000.0000 0001.0000 0001.1100 0000 - 200.1.1.192 255.255.255.192
Range :200.1.1.193 - 200.1.1.222
Divide the steps : 1、 Written in binary
2、 Calculate the number of borrowed places as required
3、 The connected bits are arranged and combined
4、 Written in decimal
eg.192.168.1.0 255.255.255.128 It needs to be divided into 4 Net segment , And write the IP Address range ?
1100 0000.1010 1000.0000 0001.0XX0 0000
1111 1111 .1111 1111 .1111 1111 . 1110 0000 Subnet mask
192.168.1.0/27(27: The subnet mask has 27 A network bit )
1100 0000.1010 1000.0000 0001.0000 0000——192.168.1.0 255.255.255.224
Range :192.168.1.1-192.168.1.30 (30:2^5-1-1;5: Subnet mask host bits )
1100 0000.1010 1000.0000 0001.0010 0000——192.168.1.32 255.255.255.224
Range :192.168.1.33-192.168.1.62 (62: 32 +30)
1100 0000.1010 1000.0000 0001.0100 0000——192.168.1.64 255.255.255.224
Range :192.168.1.65-192.168.1.94
1100 0000.1010 1000.0000 0001.0110 0000——192.168.1.96 255.255.255.224
Range :192.168.1.97-192.168.1.126
Subnet summary :
Summarize multiple network segments into one network segment ( Small network segment : Use a network segment to represent multiple network segments )( increase IP Address )
Method : Take phase parity , Go to different places
eg.10.1.1.0/24
10.1.2.0/24
10.1.3.0/24
0000 1010.0000 0001.0000 0001.0000 0000
0000 1010.0000 0001.0000 0010.0000 0000
0000 1010.0000 0001.0000 0011.0000 0000
The same bit removed is the network bit ; After the network bit is taken out, the rest is the host bit
result :10.1.0.0 /22 (22: The subnet mask has 22 A network bit )
