#The only thing I can think of that might work would be to create ssh aliases for your hosts. In your .ssh/config:

Host de.1.before
  HostName 192.26.32.32
  Port 22

Host de.1.after
  HostName 192.26.32.32
  Port 8888

#Then use these aliases in your Ansible inventory:

[de-servers-before]
de.1.before

[de-servers-after]
de.1.after
