Hi,

I want to gather all the NICs and its IP address from facts. So I tried iterating to all interfaces, i.e

{% for nic in ansible\_interfaces %}  
{% set present\_nic = ‘facter\_ipaddress\_%s’ | format( nic ) %}

> {{ nic }} | {{ present\_nic }} |  
> {% endfor %}

The present\_nic variable turn into some form of string and won’t evaluate object anymore. ☹

I wanted to grab the value of 'facter\_ipaddress\_{{ nic }} key, but instead got a literal string.

> _NIC_ | _IP_ | _Netmask_ |  
> lo | facter\_ipaddress\_lo |  
> enp0s3 | facter\_ipaddress\_enp0s3 |  
> enp0s8 | facter\_ipaddress\_enp0s8 |

Is there a way to get around with this, without resorting to writing a custom facts/module?

TIA,  
Lupin

{% for nic in ansible\_interfaces %}

> {{ nic }} | {{ hostvars[inventory\_hostname]['facter\_ipaddress\_' + nic]

}} |  
{% endfor %}
