python增加ipaddress [英] python increment ipaddress

问题描述

我想增加一个固定值的IP地址.

这正是我想要实现的目标，我有一个 IP 地址，例如 192.168.0.3 并且我想将它增加 1 这将导致 192.168.0.4 或什至是一个固定值，x 以便它将我的 IP 地址增加该数字.所以，我可以有一个像 192.168.0.3+x 这样的主机.

我只想知道此转换是否已经存在任何模块.

我尝试了 socket.inet_aton 和 socket.inet_ntoa，但我不知道如何让它正常工作.需要一些帮助或建议.

解决方案

在 Python 3 中:

<预><代码>>>>导入ip地址>>>ipaddress.ip_address('192.168.0.4') # 接受 IPv4 和 IPv6 地址IPv4Address('192.168.0.4')>>>整数(_)3232235524>>>ipaddress.ip_address('192.168.0.4') + 256IPv4Address('192.168.1.4')

反过来:

<预><代码>>>>ipaddress.ip_address(3232235524)IPv4Address('192.168.0.4')>>>字符串(_)'192.168.0.4'>>>ipaddress.ip_address('192.168.0.4') -1IPv4Address('192.168.0.3')

Python 2/3

您可以使用 struct 模块来解包 inet_aton() 的结果，例如，

导入结构体，socket# x.x.x.x 字符串 ->整数ip2int = lambda ipstr: struct.unpack('!I', socket.inet_aton(ipstr))[0]打印(ip2int(192.168.0.4"))# ->3232235524

反过来:

int2ip = lambda n: socket.inet_ntoa(struct.pack('!I', n))打印(int2ip(3232235525))# ->192.168.0.5

I would like to increment an ip address by a fixed value.

Precisely this is what I am trying to achieve, I have an ip address say, 192.168.0.3 and I want to increment it by 1 which would result in 192.168.0.4 or even by a fixed value, x so that it will increment my ip address by that number. so, I can have a host like 192.168.0.3+x.

I just want to know if any modules already exist for this conversion.

I tried socket.inet_aton and then socket.inet_ntoa, but I don't know how to get that working properly. Need some help or advice on that.

解决方案

In Python 3:

>>> import ipaddress
>>> ipaddress.ip_address('192.168.0.4')  # accept both IPv4 and IPv6 addresses
IPv4Address('192.168.0.4')
>>> int(_)
3232235524

>>> ipaddress.ip_address('192.168.0.4') + 256
IPv4Address('192.168.1.4')

In reverse:

>>> ipaddress.ip_address(3232235524)
IPv4Address('192.168.0.4')
>>> str(_)
'192.168.0.4'

>>> ipaddress.ip_address('192.168.0.4') -1
IPv4Address('192.168.0.3')

Python 2/3

You could use struct module to unpack the result of inet_aton() e.g.,

import struct, socket

# x.x.x.x string -> integer
ip2int = lambda ipstr: struct.unpack('!I', socket.inet_aton(ipstr))[0]
print(ip2int("192.168.0.4"))
# -> 3232235524

In reverse:

int2ip = lambda n: socket.inet_ntoa(struct.pack('!I', n))
print(int2ip(3232235525))
# -> 192.168.0.5
