代码中好像是转到虚拟IP的23端口 不知道什么用意 大佬可以解释下吗 如何做防域名污染呢

NSP是可以做防止域名污染的哦,禁止其它的同类型的NSP(提供域名服务 /NS)自己编写可以翻墙到境外的DNS代理服务器,由其进行DNS/53端口协议数据报的转发(那么获取到的DNS就不是被污染过的);;;当然除了NSP也可以手动编写本地的DNS环路服务器(相对容易点而且易于调试)。
Sorry, something went wrong.
请问本地环路dns服务器是个这么原理?
类似,但基于NSP的方法不是本地环路,在NSP(namespace service provider / 名称服务提供者)实现一个虚拟的仅针对目标应用的DNS服务器(用来伪造 Fuck IP 与域名之间的一一对应关系)。
当然也可以是让系统使用 localhost (一般是127.0.0.1)上的DNS本地环路服务器(自己做的虚拟服务器) 在程序退出的时候,把系统使用 dns 改为原始DNS或者直接8.8.8.8/8.8.4.4都可以。在刷新一次系统的DNS缓存
