Hi,

I want to convert the IP address to hexadecimal format. Can you please tell me how to do it in ansible/jinja2? Below is my playbook.

- name: Generate the routes and store in file  
set\_fact:

variable: “[{% for i in range(0,256,16) %}{% for j in range(0,256,1) %}‘120.100.{{ j }}.{{ i }}’,{% endfor %}{% endfor %}]”

- name: Dump the routes  
debug: var=variable

Thanks,  
Madhu

I looked at it. How do you use it in the tasks or variable file?
