Recently, the most powerful Internet vulnerability in history-the DNS Cache vulnerability. This Vulnerability refers to a vulnerable security system on the Internet in our applications. The root cause of poor security lies in design defects. By exploiting this vulnerability, users may not be able to open the webpage. The most important is phishing and financial fraud, which can cause huge losses to victims.
DNS cache poisoning attacks refer to attacks that trick the DNS server into believing the authenticity of forged DNS responses. This type of attack aims to redirect victims who depend on this DNS server to other addresses, for exa

Most DNS cache servers exist in small enterprises. they are not responsible for domain name resolution and are only used to help users query domain name information from other DNS servers. The queried information is saved locally to facilitate the next use of the domain name. it is valid to shorten the domain name query time and save the local information. The fo
