  <p>Then i went to DNS manager. I created a new Forward Primary zone and reverse zone. Here is the screen shot</p>

  <p>Then i created the record (A, MX, CNAME). Here are the screen shots of each</p>

  <p>CNAME:</p>

  <p>Reverse lookup Zone:</p>
  
  <p><img src="https://i.stack.imgur.com/Z4MXj.png" alt="Reverse Lookup Zone"></p>
  
  <p>After all that when i do nslookup, then i get Default Server: Unknown. Why ? Why i am getting unknown server</p>
