IPv6地址Python

Question

我的IPv6地址等于“2001：200：e000 :: / 35”。 但是，我无法从库ipaddress中的函数ip_address（）输入它。 该函数适用于不包含“/”的地址，例如IPv4“1.0.0.0”和IPv6“2001：12f8：0：17 :: 23”：

            @Override

            }

            @Override
            public void onCancelled(DatabaseError databaseError) {

            }

    }

    private String chat_msg,chat_user_name;

    private void append_chat_conversation(DataSnapshot dataSnapshot) {

        Iterator i = dataSnapshot.getChildren().iterator();

        while (i.hasNext()){

               chat_msg = (String) ((DataSnapshot)i.next()).getValue();
            chat_user_name = (String) ((DataSnapshot)i.next()).getValue();

            chat_conversation.append(chat_user_name +" : "+chat_msg +" \n");
        }

        
    }
   
  
}

返回：

ipaddress.ip_address(unicode("1.0.0.0","utf-8"))

并且

IPv4Address(u'1.0.0.0')

返回：

ipaddress.ip_address(unicode("2001:12f8:0:17::23","utf-8"))

然而，当我尝试使用IPv6“2001：200：e000 :: / 35”时，

IPv6Address(u'2001:12f8:0:17::23')

返回：

ipaddress.ip_address(unicode("2001:200:e000::/35","utf-8"))

我应该如何输入包含“/”的IP地址到ip_address？

Answer 1

＆＃34;带/在其中的IP地址＆＃34;你打电话给他们实际上并不是IP地址。它们是IP网络（意思是一系列IP地址），称为＆＃34; CIDR表示法＆＃34;。

您可以使用ipaddress.ip_network()处理IP网络。例如：

>>> ipn = ipaddress.ip_network("2001:200:e000::/35")
>>> ipn.num_addresses
