PythonのIPv4範囲（開始点と終了点）をスラッシュ表記に変換しますか？

Question

開始および終了IPアドレスをスラッシュ表記に変換するためのスクリプトがありますか？

例：

>>> ip_long = '10.182.71.0-10.182.75.255' 
>>> convert_to_slash(ip_long) 
10.182.71.0/24, 10.182.72.0/22 

Answer 1

Google's ipaddr-py libraryはsummarize_address_range（最初、最後）と呼ばれるメソッドを有します。

summarize_address_range(first, last): 
"""Summarize a network range given the first and last IP addresses. 

Example: 
    >>> summarize_address_range(IPv4Address('1.1.1.0'), 
     IPv4Address('1.1.1.130')) 
    [IPv4Network('1.1.1.0/25'), IPv4Network('1.1.1.128/31'), 
    IPv4Network('1.1.1.130/32')] 

Args: 
    first: the first IPv4Address or IPv6Address in the range. 
    last: the last IPv4Address or IPv6Address in the range. 

Returns: 
    The address range collapsed to a list of IPv4Network's or 
    IPv6Network's. 

Raise: 
    TypeError: 
     If the first and last objects are not IP addresses. 
     If the first and last objects are not the same version. 
    ValueError: 
     If the last object is not greater than the first. 
     If the version is not 4 or 6.

別の解決策：

from ipaddress import IPv4Address, summarize_address_range 

a=" ".join(map(str, summarize_address_range(IPv4Address('8.8.8.8'), IPv4Address('8.8.9.1')))) 

print(a)
