如何使用Python从CIDR地址生成IP地址?
在这篇文章中,我们将学习如何从CIDR地址生成IP地址。
使用的方法
以下是完成此任务的各种方法:
生成IPv4网络地址
生成IPv6网络地址
访问CIDR地址的IP地址
方法1:IPv4Network
算法(步骤)
以下是执行所需任务的算法/步骤:
使用`import`关键字导入`ipaddress`模块。
使用`ipaddress`模块的`ip_network()`函数(返回地址的网络类型)从输入的CIDR地址(IPv4Network)获取IP地址。
使用`for`循环遍历上述IPv4地址列表。
打印列表中当前的IPv4地址。
示例
以下程序从给定的CIDR地址返回IPv4地址列表:
# importing ipaddress module import ipaddress # getting the IP addresses from an input CIDR address(IPv4 network address) netIpv4Address = ipaddress.ip_network('123.45.66.64/27') print("The Following are the IPv4 Addresses in the given CIDR Address(123.45.66.64/27)") # traversing through the above IPv4 addresses list for i in netIpv4Address: # printing the current IPv4 address print(i)
输出
执行上述程序后,将生成以下输出:
The Following are the IPv4 Addresses in the given CIDR Address(123.45.66.64/27) 123.45.66.64 123.45.66.65 123.45.66.66 123.45.66.67 123.45.66.68 123.45.66.69 123.45.66.70 123.45.66.71 123.45.66.72 123.45.66.73 123.45.66.74 123.45.66.75 123.45.66.76 123.45.66.77 123.45.66.78 123.45.66.79 123.45.66.80 123.45.66.81 123.45.66.82 123.45.66.83 123.45.66.84 123.45.66.85 123.45.66.86 123.45.66.87 123.45.66.88 123.45.66.89 123.45.66.90 123.45.66.91 123.45.66.92 123.45.66.93 123.45.66.94 123.45.66.95
方法2:IPv6Network
将IPv6网络的CIDR地址作为参数传递给`ip_network()`函数,并通过遍历结果打印其所有IPv6网络。
示例
以下程序从给定的CIDR地址返回IPv6地址列表:
# importing ipaddress module import ipaddress # getting the IP addresses from an input CIDR address(IPv6 network address) netIpv6Address = ipaddress.ip_network('12:3456:78:90ab:cd:ef11:23:30/125') print("The Following are the IPv6 Addresses in the given CIDR Address(12:3456:78:90ab:cd:ef11:23:30/125)") # traversing in the above Ipv6Address for i in netIpv6Address: # printing the current Ipv6Address print(i)
输出
执行上述程序后,将生成以下输出:
The Following are the IPv6 Addresses in the given CIDR Address(12:3456:78:90ab:cd:ef11:23:30/125) 12:3456:78:90ab:cd:ef11:23:30 12:3456:78:90ab:cd:ef11:23:31 12:3456:78:90ab:cd:ef11:23:32 12:3456:78:90ab:cd:ef11:23:33 12:3456:78:90ab:cd:ef11:23:34 12:3456:78:90ab:cd:ef11:23:35 12:3456:78:90ab:cd:ef11:23:36 12:3456:78:90ab:cd:ef11:23:37

方法3:访问CIDR地址的IP地址
我们可以通过将所有对应的IP地址作为列表获取,并使用`[]`运算符(即索引方法)访问列表元素来访问给定CIDR地址的IP地址。
示例
以下程序演示如何访问CIDR地址的IP地址:
# importing ipaddress module import ipaddress # getting the IP addresses from an input CIDR address(IPv4 network address) netIpv4Address = ipaddress.ip_network('123.45.66.64/27') # accessing the first Ipv4Address from the resultant list print("First Ipv4Address from the list:", netIpv4Address[0]) # accessing the second Ipv4Address from the resultant list print("Second Ipv4Address from the list:", netIpv4Address[1]) # accessing the last Ipv4Address from the resultant list print("Last Ipv4Address from the list:", netIpv4Address[-1])
输出
执行上述程序后,将生成以下输出:
First Ipv4Address from the list: 123.45.66.64 Second Ipv4Address from the list: 123.45.66.65 Last Ipv4Address from the list: 123.45.66.95
结论
本文教我们如何从提供的CIDR地址中提取每个IP地址。我们使用了两种方法,一种用于获取所有IPv4地址,另一种用于收集IPv6地址。我们还展示了如何在将IP地址转换为列表后使用`[]`运算符访问它们。
