\"How<\/p>\n

The ‘DiG’ command, short for “Domain Information Groper,” is a versatile tool used for querying DNS (Domain Name System) servers. It is part of the BIND (Berkeley Internet Name Domain) utilities package. Webmasters and system administrators often use dig to troubleshoot DNS-related issues, fetch domain records, and gain insights into how domain names are resolved.<\/p>\n

For those who are familiar with web servers<\/a>, ‘dig’ is an essential tool, especially when working with platforms like Apache<\/a>, Nginx<\/a>, and LiteSpeed<\/a>. Whether you’re on a dedicated server<\/a>, VPS server<\/a>, cloud hosting<\/a>, or even a shared hosting<\/a> environment, understanding how to use ‘dig’ can be beneficial.<\/p>\n

In this tutorial, we will walk you through the process of installing ‘dig’ on an Ubuntu<\/a> system, step by step.<\/p>\n

Let’s get started.<\/p>\n

Step 1: Update the Package Repository<\/h2>\n

Before installing any new software on Ubuntu, it’s a good practice to update the package repository to ensure you’re getting the latest version.<\/p>\n

sudo apt update<\/pre>\n
Step 2: Install the BIND Utilities<\/h2>\n
The ‘dig’ command is part of the BIND utilities package. To install it, use the following command:<\/p>\n
sudo apt install dnsutils<\/pre>\n
Step 3: Verify the Installation<\/h2>\n
Once the installation is complete, you can verify that ‘dig’ has been installed correctly by typing:<\/p>\n
dig -v<\/pre>\n
This command should return the version of ‘dig’ that you’ve installed.<\/p>\n
for example:<\/p>\n
\r\nroot@geeks:~# dig -v\r\nDiG 9.11.3-1ubuntu1.18-Ubuntu\r\n<\/pre>\n
Step 4: Using ‘dig’<\/h2>\n
To use ‘dig’, simply type the command followed by the domain you wish to query. For example:<\/p>\n
dig example.com<\/pre>\n
This will return a standard DNS query for the domain “example.com”.<\/p>\n
For example:<\/p>\n
\r\nroot@geeks:~# dig example.com\r\n; <<>> DiG 9.11.3-1ubuntu1.18-Ubuntu <<>> example.com\r\n;; global options: +cmd\r\n;; Got answer:\r\n;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 29809\r\n;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 1\r\n\r\n;; OPT PSEUDOSECTION:\r\n; EDNS: version: 0, flags:; udp: 4096\r\n;; QUESTION SECTION:\r\n;example.com.
