This process is generally refers to the process of responding a DNS request that was supposed to implement for another server. This can be in the case where the secondly DNs system is implemented where the DNS server request another server for mapping. Also in the case of client server dialog, when a client sends request to DNS for mapping purpose. The hacker simply insertsor can say stuff the DNS server’s answer. This results in the processing of answer by answering with the source-address field by DNS server’s IP address in the packets’. Although this is not an easy way to modify the DNS reply.

The DNS cache of the impersonated DNS can be done without touching the DNS cache.
