Hello,

I’m strugling with the additional IP address fact for Ansible

```auto
"ansible_eth0_1": {
    "active": true, 
    "device": "eth0_1", 
    "ipv4": {
        "address": "192.168.10.2", 

```

Playbook says that eth0\_1.ipv4.address is undefined variable.

What you can suggest for these variables?

You have forgotten ansible\_ in front of the variable.
