IPy Module introduction
IPy This powerful Python The third-party package mainly provides network segments 、 Network mask 、 Broadcast address 、 Number of subnets 、IP Type processing and other functions .

IPy Module USES
Call module
Use IPy When the module , You need to call the module first
from IPy import IP
Define network segment
ip = IP('10.0.0.0/24')
Query the network segment IP Number
Use len() function
ip.len()
256
for i in ip.len(): # Traverse network segment IP
print(i)
IP address translation
Use reverseName() Function pair IP Reverse parsing
ip1 = IP('192.168.4.111')
ip1.reverseName()
'111.4.168.192.in-addr.arp
see IP type
Use iptype() The function view IP type
ip1 = IP('192.168.4.111')
ip1.iptype()
PRIVATE
take IP Format conversion to other types of formats
ip1 = IP('192.168.4.111')
ip1.int() # int() function
3232236655
ip1.strHex() # 16 Base number
'0xc0a8046f'
ip1.strBin() # 2 Base number
'11000000101010000000010001101111'
print(IP(0xc0a80101)) # take 16 The base number is converted to IP Format
192.168.1.1
Judge IP The network segment
ip = IP('192.168.4.159')
Writing form 1 ：
print(ip.make_net(26))
192.168.4.128/26
Writing form 2 ：
print(ip.make_net(255.255.225.192))
192.168.4.128/26
print(IP('192.168.4.0-192.168.4.255',make_net=True)) # This network segment must be a subnet mask 255.255.225.0 The network segment
192.168.4.0/24
Different output formats of network segments
strNormal() Output IP Different formats of network segments
Parameters ：
0： Output the network ID of the network segment
1： With prefix Output network segment in the form of
2： With decimalnetmask Output network segment in the format of
3： With lastIP Output network segment in the format of
print(IP('192.168.1.0/24').strNormal(0)) # Output the network ID of the network segment
192.168.1.0
print(IP('192.168.2.0/26').strNormal(1)) # Output network segment
192.168.2.0/6 # Output prefix Format segment
print(IP('192.168.3.0/24').strNormal(2))
192.168.2.0/255.255.255.192 # Output decimalnetmask Format segment
print(IP('192.168.4.0/24').strNormal(3))
192.168.2.0-192.168.2.63 # Output lastIP Format
Judge whether the two network segments contain or overlap
Determine the network segment size
The basis of comparison ： Compare the network bits , Compare values from left to right , To be able to distinguish is to compare , The non network bit must be 0
IP("10.0.0.0/24") < IP("12.0.0.0/16") # True 12.0.0.0/16 Large network segment
IP("13.0.0.0/8") < IP("12.5.5.0/26") # False 13.0.0.0/8 Large network segment
Judge IP Whether the address and network segment are contained in another network segment
**in：** Judge iIP Or whether the network segment is in another network segment China
"192.168.1.55" in IP("192.168.1.0/24") # True
IP("192.168.4.64/26") in IP("192.168.4.0/24") # True
Determine whether the two network segments overlap
IP("192.168.4.0/26").overlaps("192.168.4.0/24") # 1 1 Indicates that two network segments overlap
IP("10.0.0.0/26").overlaps("10.0.2.0/24") # 0 0 Indicates that two network segments do not overlap
Output the network address of the network segment 、 Subnet mask and broadcast address
ip = IP("192.168.6.0/24")
ip.net() # IP('192.168.6.0')
ip.netmask() # IP('255.255.255.0')
ip.broadcast() # IP('192.168.6.255')
