Calculate the CIDR block address and broadcast address (original) based on the IP address and subnet mask. in Python, there is an IP class library dedicated to this type of problem. Let's take a look:
View sourceprint? 01 #! /Usr/bin/ENV Python

03 import sys
04 from IPY import IP
05
06 address = SYS. argv [1]
07 netmask = SYS. argv [2]
08
09 # print address, netmask
10
11 # Help (IP)
12 networkaddress = IP (Address). make_net (netmask) # init a IP instance, can with netmask directly, or use make_net (netmask)
13 bcastaddress = IP (networkaddress). Broadcast () # Return the broadcast IP Address
14
15 print networkaddress
16 print bcastaddress
