title: What does 'No such name' mean in DNS?
body: <p>So i'm currently using Wireshark to investigate DNS traffic. In the command prompt, i am running the query <code>nslookup</code> to lookup a domain. In wireshark i am getting the following response:</p>
  
  <pre><code>Flags: 0x8183 Standard query response, No such name
      1... .... .... .... = Response: Message is a response
      .000 0... .... .... = Opcode: Standard query (0)
      .... .0.. .... .... = Authoritative: Server is not an authority for domain
      .... ..0. .... .... = Truncated: Message is not truncated
      .... ...1 .... .... = Recursion desired: Do query recursively
      .... .... 1... .... = Recursion available: Server can do recursive queries
      .... .... .0.. .... = Z: reserved (0)
      .... .... ..0. .... = Answer authenticated: Answer/authority portion was not authenticated by the server
      .... .... ...0 .... = Non-authenticated data: Unacceptable
      .... .... .... 0011 = Reply code: No such name (3)
  </code></pre>
  
  <p>What exactly does 'No such name' mean and why is it being displayed?</p>
