When the victim requests a DNS query, fake information is presented by the hacker, which results in visiting a site that you didn’t want to. For example, if you want to visit a site www.example.com, you would be directed to another site due to the spoofed queries.
The Attacker Responds To The DNS Request Earlier Than The Actual Response
When a DNS query is made, the hacker and tries to respond as soon as possible, before the actual query response.
The IP Address Is Changed
You would be wondering how you are made to visit another site while querying for the original one. That is done by changing the IP Address. When the user requests a query, the IP address is changed, which makes the user visit another site.
