Ansible facts are pieces of information regarding the remote systems to which you have connected. These are very useful for scenarios where you need to take conditional operations based on the remote machines state. For example, depending on the OS version used by the remote server you can install the different versions of a package. By default, whenever you run a task on the remote server, all the facts about that systems are captured.
Ansible provides a setup module to gather all the information regarding the remote servers.
It can be run from the command line to see the data. If you want to see all the variables captured by the setup module, you can use the following command. This will give a large dump of data like below. You can scroll in the below box. This lists all facts in Ansible. It is possible to filter data from this. Suppose you need all the info regarding the operating system the remote machine uses, then you can give the following command. The above examples showed the facts retrieved via command line.
But we need to get the output in Ansible task for more meaningful tasks. In order to retrieve the previous output OS info in an ansible task, you can do the following. But you can give the variable name by itself in every case. From the large dump, you can see the mac address is avaible in two locations.

The reason why this behavior happens is because you have no default routes defined for your IPv4 or IPv6 addresses. I was able to reproduce this on CentOS 7. Looks like desired behavior and a non-issue to me:. Thank you. In my case there is a LAN and there is no gateway in it.
The ansible control host and the remote host are in this LAN. So, sudomateothere is no problem at all, to determine default interface on the remote host. Please, correct me if I am wrong.

While running a Playbook you might have had a requirement where you need to get the IP address of the connected and current remote host. Sometimes the Default IPv4 address of the remote host is not the one you are looking for or it is not the one you have used to connect. So the question is How do you get the IP address. In this article, we are going to see various methods to get that Done including the obvious Default IPv4 and eth0 choice.
But the First one is my favourite and proved to be giving the IP address of the remote host I want. In this method, we are going to use the IP address used by Ansible master to connect to the Remote Host. Sometimes, we would use the public IP to connect to the remote host in such cases we would want to use this method. This is the method I have been using for a while and It never failed me.Ansible Playbooks for Cisco Network Automation!
So in this method. Check this post. The following playbook would show how to get the IP address of the remote target or host using the SSH Connection between the ansible master and the host. Also, this is the IP being used to ansible master to connect to the target, so this can be used as the Righteous IP in all requirements.
The method would not work. There is another best example you can refer for this method.
In such cases, the following playbook or method would help you to get the IP address of the remote host. Mostly the Linux servers used to have eth0 as the default network interface name but this tradition is becoming an era. This can be used in AWS on certain circumstances but this would reveal only the private IP address not the public ip. You can see we have used the interface names to fetch the IP address of the connected target host.
You can see the different interfaces have different IP addresses. You can choose this method if you are looking to get the IP address based on the interface name.
So these are the three different methods to get the IP address of the remote hosts. If you feel that there is more feel free to comment and let the readers know.
