So I’m trying to get the IP address of every server via `ansible` and expect to use something like ansible -i inventory host\_group -m setup -a filter=“ansible\_eth0.ipv4.address” returns no results. It returns something like ` server38.prod.foo | success \>\> { “ansible\_facts”: {}, “changed”: false } ` But I can do ansible -i inventory host\_group -m setup -a filter=“ansible\_eth0” and it will return: ` server38.prod.foo | success \>\> { “ansible\_facts”: { “ansible\_eth0”: { “active”: true, “device”: “eth0”, “ipv4”: { “address”: “1.2.3.4.”, “netmask”: “255.255.255.0”, “network”: “1.2.3.0” }, “ipv6”: [ { “address”: “fe11::225:90ff:fe11:1111”, “prefix”: “64”, “scope”: “link” } ], “macaddress”: “00:11:11:11:11:11”, “module”: “e1000e”, “mtu”: 1500, “promisc”: false, “type”: “ether” } }, “changed”: false } ` So it does return facts…how do I get filter further to return just the IP address? ---

One of the notes in the docs of the setup module reads: "the filter option filters only the first level subkey below ansible\_facts." So you don't. Not that way at least. What about ansible\_all\_ipv4\_addresses? ---

Yeah, I’m aware of ansible\_all\_ipv4\_addresses but that shows all interfaces and I just want eth0. Assuming that list is eth0, eth1, etc. etc. then I guess I could just take the first item in the list. ---

Not a straight way but a roundabout way ansible -i inventory host\_group -m setup -a filter=“ansible\_eth0”|grep -A1 ipv4|tail -1|cut -d: -f2|cut -d""" -f2 Need to check if there are different ways to extract it. ---

Igor, I’ve been googling a bit and can’t find what the difference between facter\_ipaddress\_eth1 and ansible\_eth0.ipv4.address is. Could you please clarify? ---

If facter (a Puppet utility) is installed on the node, ansible picks up those facts along with its own. ---

The difference might be a non-existing interface 😉 facter is requested to show the address of interface "eth1" while ansible should show the address of "eth0". D&r Werner Agusti Tomas [18.08.2016 17:16]: ---

Werner, Yes, that was a typo, but if it would have been ansible\_eth1.ipv4.address, would the expressions have been equivalent? ---

Waaah, reading the docs might make that clear: 2nd note on \<[http://docs.ansible.com/ansible/setup\_module.html>:](http://docs.ansible.com/ansible/setup_module.html>:) The filter option filters only the first level subkey below ansible\_facts. And since the first level subkey is "ansible\_eth1", the filter does not look deeper. Facter's most facts are not nested (except for e.g. facter\_os), so this works better in the given case.

I got facter to install via playbook now on my CentOS 7 box and the first time it runs the playbook it doesn’t find the facter\_ipaddress\_eth1 but it does find it the second time I run the playbook. Do you know if there should be some waiting time after installing facter? ---

I am not aware of an after-installation pause. Do you use some cache for facts, like redis? There may be a timeout during the collection of facts, as I can see at my box (not Centos, but SLES), the runtime is either short or quite long - maybe some facts are hard to detect.
