Ansible: How to increment IP address?

Question

I am passing a variable to Ansible with --extra-vars "lan=10.10.10.1".

I now need to increment this IPaddress so that the last octet is .2 so it will equal 10.10.10.2.

How would this be achieved in Ansible?

Answer 1

As of Ansible 2.7 this can be done using IP Math:

{{ lan | ipmath(1) }}
