ipaddr_filter's Introduction

ipaddr filter examples

The ipaddr filter is a Jinja2 filter designed to provide an interface to netaddr. This github repo provides examples with the Ansible template module to augment the ipaddr documentation.

        dest: ./rendered

Running the playbook

The rendered config will provider numerous examples. For example:

Jinja2:  What is the range of usable IP address on {{sean_subnet}}? {{ sean_subnet | ipaddr('range_usable') }}
Renders:  What is the range of usable IP address on 192.168.1.0/24? 192.168.1.1-192.168.1.254
