This article mainly explains "how to solve the problem of DNS pollution". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to solve the problem of DNS pollution.

There is generally no other way to deal with DNS pollution than to use a proxy server. However, using our understanding of DNS pollution, we can still solve the problem of DNS pollution without a proxy server, so as to visit some websites that can not be accessed without using a proxy server.

Of course, this does not solve all the problems, when some inaccessible websites themselves are not caused by DNS pollution, you still need to use a proxy server to access them.

DNS-contaminated packets are generated not on the router where the network packet passes, but on its bypass. Therefore, DNS contamination can not prevent the correct DNS parsing results from returning, but because the data packets generated by bypass are sent back faster than those sent back by foreign DNS servers, the operating system thinks that the first received data packet is the return result, thus ignoring the subsequent received data packets, thus making DNS contamination successful.

However, the pollution IP of DNS pollution in some countries is fixed for a period of time, so we can ignore the packets that return these IP addresses and solve the problem of DNS pollution directly.

DNS pollution solution

1. Use various SSH encryption agents to perform remote DNS parsing in the encryption agent.

2. Modify the hosts file. The permission priority of the Hosts file in the operating system is higher than that of the DNS server. When the operating system accesses a domain name, it will first detect the HOSTS file, and then query the DNS server. You can add contaminated DNS addresses to hosts to resolve DNS contamination and DNS hijacking.

3. Through some programming processing, the data packets with false IP addresses can be ignored directly, and the problem of DNS pollution can be solved directly.

4. If you are Firefoxonly, just open the remote DNS parsing of Firefox directly. In the address bar, enter:

About:config

Find network.proxy.socks_remote_dns and change it to true.

At this point, I believe you have a deeper understanding of "how to solve the problem of DNS contamination". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
