    其他常用方法介绍:
    | __cmp__(self, other) —— 比较大小
    | Called by comparison operations.
    |
    | Should return a negative integer if self < other, zero if self
    | == other, a positive integer if self > other.
    |
    | Networks with different prefixlen are considered non-equal.
    | Networks with the same prefixlen and differing addresses are
    | considered non equal but are compared by their base address
    | integer value to aid sorting of IP objects.
    |
    | The version of Objects is not put into consideration.
    |
    | >>> IP('10.0.0.0/24') > IP('10.0.0.0')
    | 1
    | >>> IP('10.0.0.0/24') < IP('10.0.0.0')
    | 0
    | >>> IP('10.0.0.0/24') < IP('12.0.0.0/24')
    | 1
    | >>> IP('10.0.0.0/24') > IP('12.0.0.0/24')
    | 0
    | __contains__(self, item) —— 检查包含关系
    | Called to implement membership test operators.
    |
    | Should return true if item is in self, false otherwise. Item
    | can be other IP-objects, strings or ints.
    |
    | >>> IP('195.185.1.1').strHex()
    | '0xc3b90101'
    | >>> 0xC3B90101 in IP('195.185.1.0/24')
    | True
    | >>> '127.0.0.1' in IP('127.0.0.0/24')
    | True
    | >>> IP('127.0.0.0/24') in IP('127.0.0.0/25')
    | False
    | overlaps(self, item) —— 检查是否重叠
    | Check if two IP address ranges overlap.
    |
    | Returns 0 if the two ranges don't overlap, 1 if the given
    | range overlaps at the end and -1 if it does at the beginning.
    |
    | >>> IP('192.168.0.0/23').overlaps('192.168.1.0/24')
    | 1
    | >>> IP('192.168.0.0/23').overlaps('192.168.1.255')
    | 1
    | >>> IP('192.168.0.0/23').overlaps('192.168.2.0')
    | 0
    | >>> IP('192.168.1.0/24').overlaps('192.168.0.0/23')
    | -1

    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 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
