根据ip地址和子网掩码计算网段地址和广播地址（原创） Python里有一个专门处理该类问题的IP类库，来看看：
view sourceprint?01 #! /usr/bin/env python 02
03 import sys
04 from IPy import 娇气的玫瑰/p>
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
