How To Use NSLOOKUP to View DNS Records


Definition: 
nslookup is a network administration command-line tool available in many computer operating systems for querying the Domain Name System (DNS) to obtain domain name or IP address mapping, or other DNS records.
You may find the need to check the status of your domains DNS records, or check the Name Servers to see which records the servers are pulling. 

  1.  Launch Windows Command Prompt by navigating to Start > Command Prompt or via Run > CMD.
  2. Type NSLOOKUP and  Enter.  The default Server is set to your local DNS, the Address will be your local IP.
  3. Set the DNS Record type you wish to lookup by typing set type=## where ## is the record type, then hit Enter.  You may use A, AAAA, A+AAAA, ANY, CNAME, MX, NS, PTR, SOA, or SRV as the record type. The default type is A record.
  4. Now enter the domain name you wish to query then hit Enter..  In this example, we will use Managed.com.  
  5. NSLOOKUP will now return the record entries for the domain you entered. 
  6. You can also change the Name Servers which you are querying.  This is useful if you are checking the records before DNS has fully propagated.  To change the Name Server type server [name server].  Replace [name server] with the Name Servers you wish to use.  In this example, we will set these as dns.google.  
  7. Once changed, change the query type (Step 4), But since we connected to public address (Google DNS) we can not resolve the private addresses. So we are trying to resolve a public address.
