推荐答案

您计划生成的密钥永远不会唯一.
您将有可能重复此组合(因为只有6个字符).

改为使用GUID [

This key that you plan to generate can never be unique.
You will have a possibility of repeating this combination (since you have only 6 characters).

Use a GUID instead[^].

我会尝试使用54个大写/小写字母+ 10个数字+''?=()[] {}&％#！+''对ip地址进行编码，从而为您提供78个字符供您选择.

这足以编码任何32位值(ipv4地址为32位)，然后再编码为6个字符.

最好的问候

I''d try encoding the ip address using the 54 upper/lower case characters + the 10 digits + ''?=()[]{}&%#!+'' giving you 78 characters to choose from.

That''s sufficient to encode any 32-bit value (ipv4 address is 32 bits), and then some, in 6 characters.
