Anyone use this filter function? It seems like a lookup to see if an IP or subnet is a member of a larger prefix.

I am just not sure on the proper usage.

Thanks!

Hi,

There are some great examples on the ipaddr filter’s documentation page: https://docs.ansible.com/ansible/latest/user_guide/playbooks_filters_ipaddr.html#playbooks-filters-ipaddr

Yes, one of the things you can do is check to see if an IP belongs to a subnet.

Hello Scott,

I’m very familiar with the documented functions of the ipaddr filter. If you look at the link you just sent cidr_lookup is not a documented function, but it is listed in the source code of the filter as I linked to in my original post.

Thanks!

Scott,

I appreciate your patience here. Even when I said I am very familiar with the document, you pressed on and pointed me to the item that was right in front of my face! That worked perfectly

Thanks!
