+Please note that IPV6 is disabled in this role. If you need to by-pass this functionality because IPV6 is already being
+disabled on a system then you can accomplish this by invoking the playbook with the --skip-tags flag like this:
+
+ ansible-playbook install-edge.yml --skip-tags=ipv6
+
+Additional information regarding how Ansible uses tags can be obtained [here](http://docs.ansible.com/ansible/latest/user_guide/playbooks_tags.html).
