Introduction

The dig command is a powerful tool used for querying DNS (Domain Name System) records. It is a crucial component in network troubleshooting and DNS management. However, by default, the dig command displays a lot of additional information that may not be necessary for every query. In this article, we will explore how to use the dig command to show only the answer to your query.

Understanding the Default Output of Dig

When you run the dig command, it displays a lot of information, including:

The command prompt and version of dig
Global options used
The query you made
The server that responded to your query
The answer to your query
Additional information, such as the number of records and the time it took to receive the response

The default output of dig can be overwhelming, especially when you only need to see the answer to your query. Let's take a look at an example of the default output of dig:

;; &lt;&lt;&gt;&gt; DiG 9.7.3 &lt;&lt;&gt;&gt; google.de
;; global options: +cmd
;; Got ... &lt;&lt;&gt;&gt; 8.8.8.8
;; ->>HEADER&lt;&lt;- opcode: QUERY, status: NOERROR, id: 1234
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0
;; QUESTION SECTION:
;google.de. IN A
;; ANSWER SECTION:
google.de. 300 IN A 216.58.194.174
;; Query time is 0 msec
;; SERVER: 8.8.8.8#53(8.8.8.8)
;; WHEN: Thu Mar  9 14:30:00 2023
;; MSG SIZE  rcvd: 56

How to Show Only the Answer to Your Query

To show only the answer to your query, you can use the -t option followed by the type of record you are looking for. For example, to show only the A record for google.de, you can use the following command:

dig -t A google.de

This will display only the A record for google.de, which is:

google.de. 300 IN A 216.58.194.174

Other Options to Customize the Output of Dig

In addition to the -t option, there are several other options you can use to customize the output of dig. Here are a few examples:

-c option: This option allows you to specify the name of the file that contains the DNS server's configuration.
-p option: This option allows you to specify the port number that the DNS server is listening on.
-x option: This option allows you to perform a reverse lookup on an IP address.
-y option: This option allows you to specify the type of query to perform (e.g. A, AAAA, MX, etc.).

Here are a few examples of how you can use these options:

# Specify the name of the file that contains the DNS server's configuration dig -c /etc/resolv.conf google.de dig -p 53 google.de dig -x 216.58.194.174

dig -y A google.de

Conclusion

By using these options, you can tailor the output of dig to meet your specific needs and make it easier to troubleshoot DNS issues.
