I am writing a playbook where I want to name a file including the ipaddress. However, my default ipv4 in the facts is empty, even though my interface is active and has a static ip. My target machine is CentOS 7.1, and my ansible version is 1.9.3.

**“ansible\_default\_ipv4”: {},**  
“ansible\_default\_ipv6”: {  
“address”: “REDACTED”,  
“gateway”: “REDACTED”,  
“interface”: “enp5s0”,  
–break–  
“ansible\_enp5s0”: {  
“active”: true,  
“device”: “enp5s0”,  
“ipv4”: {  
**“address”: “REDACTED”,**  
“netmask”: “255.255.255.0”,  
“network”: “REDACTED”

This might just be a configuration issue with my host. I’m still working on bootstrapping it to be my new control host. I also just realized that AWS EC2 hosts give their internal addresses, not public, so default ipv4 won’t always do what I need.

My goal is to fetch a set of ssh public\_key files gathered from remote hosts, and name them with user + the hosts’ public ip addresses. Is there a way to extract the ips from a group of hosts? I am ending up with one file rather than a file for each host when I use the following:

My task:

- name: copy new keys back to repo  
fetch: “src=/home/ansible/.ssh/id\_rsa.pub  
dest=/home/ansible/public\_keys/ansible\_{{item}}  
flat=yes”  
with\_items:
- ‘{{ hosts }}’

On the command line I specify --extra-vars “hosts=ipaservers” and end up with one file named ansible\_ipaservers with only one key in it. I’m hoping to end up with something like ansible\_52.x.x.x, ansible\_192.x.x.x, ansible\_176.x.x.x files instead, each with the ansible user’s key on that host.
