I don't think there is a lookup plugin for that, yet.
Not the cleanest way, but you could use register and dig:
vars:
some_ip: "8.8.8.8"
some_hostname: "google.com"
tasks:
- name: resolve some ip
command: "dig +short -x {{ some_ip }}"
register: resolved_ip
- debug:
var: resolved_ip.stdout
- name: resolve some hostname
command: "dig +short {{ some_hostname }}"
register: resolved_hostname
- debug:
var: resolved_hostname.stdout
