Sorry i had a typo:
if the variable is "my_int_if: eth0"
then in playbook it woudl be referenced as
host={{ hostvars[item]['ansible_' + my_int_if].ipv4.address }}
earlier i had only put "my_int"
if still it doesnt work, can you please paste your group_vars and plybook
in gist and let us know the version of ansible you are using.
