+5 Commands to Find the IP Address of a Domain in the Linux Terminal
+======
+
+This tutorial shows you how to verify a domain name’s or computer name IP address from a Linux terminal.
+
+This tutorial will allow you to check multiple domains at once.
+
+You may have already used these commands to verify information.
+
+However, we will teach you how to use these commands effectively to identify multiple domain IP address information from the Linux terminal.
+
+This can be done using the following 5 commands.
+
+  * **dig Command:** dig is a flexible cli tool for interrogating DNS name servers.
+  * **host Command:** host is a simple utility for performing DNS lookups.
+  * **nslookup Command:** Nslookup command is used to query Internet domain name servers.
+  * **fping Command:** fping command is used to send ICMP ECHO_REQUEST packets to network hosts.
+  * **ping Command:** ping command is used to send ICMP ECHO_REQUEST packets to network hosts.
+
+
+
+To test this, we created a file called “domains-list.txt” and added the below domains.
+
+```
+# vi /opt/scripts/domains-list.txt
+
+2daygeek.com
+magesh.co.in
+linuxtechnews.com
+```
+
+### Method-1: How to Find a IP Address of the Domain Using the dig Command
+
+**[dig command][1]** stands for “domain information groper”‘ is a powerful and flexible command-line tool for querying DNS name servers.
+
+It performs DNS lookups and displays the answers that are returned from the name server(s) that were queried.
+
+Most DNS administrators use dig command to troubleshoot DNS problems because of its flexibility, ease of use and clarity of output.
+
+It also has a batch mode functionality to read search requests from a file.
+
+```
+# dig 2daygeek.com | awk '{print $1,$5}'
+
+2daygeek.com. 104.27.157.177
+2daygeek.com. 104.27.156.177
+```
+
+Use the following bash script to find the multiple domain’s IP address.
+
+```
+# vi /opt/scripts/dig-command.sh
+
+#!/bin/bash
+for server in `cat /opt/scripts/domains-list.txt`
+do echo $server "-"
+dig $server +short
+done | paste -d " " - - -
+```
+
+Once the above script is added to a file. Set the executable permission for the “dig-command.sh” file.
+
+```
+# chmod +x /opt/scripts/dig-command.sh
+```
+
+Finally run the bash script to get the output.
+
+```
+# sh /opt/scripts/dig-command.sh
+
+2daygeek.com - 104.27.156.177 104.27.157.177
+magesh.co.in - 104.18.35.52 104.18.34.52
+linuxtechnews.com - 104.27.144.3 104.27.145.3
+```
+
+If you want to run the above script in one line, use the following script.
+
+```
+# for server in 2daygeek.com magesh.co.in linuxtechnews.com; do echo $server "-"; dig $server +short; done | paste -d " " - - -
+```
+
+Alternatively, you can use the following shell script to find the IP address of the multiple domain.
+
+```
+# for server in 2daygeek.com magesh.co.in linuxtechnews.com; do dig $server | awk '{print $1,$5}'; done
+
+2daygeek.com. 104.27.157.177
+2daygeek.com. 104.27.156.177
+magesh.co.in. 104.18.34.52
+magesh.co.in. 104.18.35.52
+linuxtechnews.com. 104.27.144.3
+linuxtechnews.com. 104.27.145.3
+```
+
+### Method-2: How to Find a Domain’s IP Address Using the host Command
+
+**[Host Command][2]** is a simple CLI application to perform **[DNS lookup][3]**.
+
+It is commonly used to convert names to IP addresses and vice versa.
+
+When no arguments or options are given, host prints a short summary of its command line arguments and options.
+
+You can view all types of records in the domain by adding a specific option or type of record in the host command.
+
+```
+# host 2daygeek.com | grep "has address" | sed 's/has address/-/g'
+
+2daygeek.com - 104.27.157.177
+2daygeek.com - 104.27.156.177
+```
+
+Use the following bash script to find the multiple domain’s IP address.
+
+```
+# vi /opt/scripts/host-command.sh
+
+for server in `cat /opt/scripts/domains-list.txt`
+do host $server | grep "has address" | sed 's/has address/-/g'
+done
+```
+
+Once the above script is added to a file. Set the executable permission for the “host-command.sh” file.
+
+```
+# chmod +x /opt/scripts/host-command.sh
+```
+
+Finally run the bash script to get the output.
+
+```
+# sh /opt/scripts/host-command.sh
+
+2daygeek.com - 104.27.156.177
+2daygeek.com - 104.27.157.177
+magesh.co.in - 104.18.35.52
+magesh.co.in - 104.18.34.52
+linuxtechnews.com - 104.27.144.3
+linuxtechnews.com - 104.27.145.3
+```
+
+### Method-3: How to Find the IP Address of a Domain Using the nslookup Command
+
+**[nslookup command][4]** is a program for querying Internet **[domain name servers (DNS)][5]**.
+
+nslookup has two modes, which are interactive and interactive.
+
+Interactive mode allows the user to query name servers for information about various hosts and domains or to print a list of hosts in a domain.
+
+Non-interactive mode is used to print just the name and requested information for a host or domain.
+
+It is a network administration tool that helps diagnose and resolve DNS related issues.
+
+```
+# nslookup -q=A 2daygeek.com | tail -n+4 | sed -e '/^$/d' -e 's/Address://g' | grep -v 'Name|answer' | xargs -n1
+
+104.27.157.177
+104.27.156.177
+```
+
+Use the following bash script to find the multiple domain’s IP address.
+
+```
+# vi /opt/scripts/nslookup-command.sh
+
+#!/bin/bash
+for server in `cat /opt/scripts/domains-list.txt`
+do echo $server "-"
+nslookup -q=A $server | tail -n+4 | sed -e '/^$/d' -e 's/Address://g' | grep -v 'Name|answer' | xargs -n1 done | paste -d " " - - -
+```
+
+Once the above script is added to a file. Set the executable permission for the “nslookup-command.sh” file.
+
+```
+# chmod +x /opt/scripts/nslookup-command.sh
+```
+
+Finally run the bash script to get the output.
+
+```
+# sh /opt/scripts/nslookup-command.sh
+
+2daygeek.com - 104.27.156.177 104.27.157.177
+magesh.co.in - 104.18.35.52 104.18.34.52
+linuxtechnews.com - 104.27.144.3 104.27.145.3
+```
+
+### Method-4: How to Find a Domain’s IP Address Using the fping Command
+
+**[fping command][6]** is a program such as ping, which uses the Internet Control Message Protocol (ICMP) echo request to determine whether a target host is responding.
+
+fping differs from ping because it allows users to ping any number of host in parallel. Also, hosts can be entered from a text file.
+
+fping sends an ICMP echo request, moves the next target in a round-robin fashion, and does not wait until the target host responds.
+
+If a target host replies, it is noted as active and removed from the list of targets to check; if a target does not respond within a certain time limit and/or retry limit it is designated as unreachable.
+
+```
+# fping -A -d 2daygeek.com magesh.co.in linuxtechnews.com
+
+104.27.157.177 (104.27.157.177) is alive
+104.18.35.52 (104.18.35.52) is alive
+104.27.144.3 (104.27.144.3) is alive
+```
+
+### Method-5: How to Find the IP Address of the Domain Using the ping Command
+
+**[ping command][6]** stands for (Packet Internet Groper) command is a networking utility that used to test the target of a host availability/connectivity on an Internet Protocol (IP) network.
+
+It’s verify a host availability by sending Internet Control Message Protocol (ICMP) Echo Request packets to the target host and waiting for an ICMP Echo Reply.
+
+It summarize statistical results based on the packets transmitted, packets received, packet loss, typically including the min/avg/max times.
+
+```
+# ping -c 2 2daygeek.com | head -2 | tail -1 | awk '{print $5}' | sed 's/[(:)]//g'
+
+104.27.157.177
+```
+
+Use the following bash script to find the multiple domain’s IP address.
+
+```
+# vi /opt/scripts/ping-command.sh
+
+#!/bin/bash
+for server in `cat /opt/scripts/domains-list.txt`
+do echo $server "-"
+ping -c 2 $server | head -2 | tail -1 | awk '{print $5}' | sed 's/[(:)]//g'
+done | paste -d " " - -
+```
+
+Once the above script is added to a file. Set the executable permission for the “dig-command.sh” file.
+
+```
+# chmod +x /opt/scripts/ping-command.sh
+```
+
+Finally run the bash script to get the output.
+
+```
+# sh /opt/scripts/ping-command.sh
