Probably something like

hostvars[groups['webservers']|first].new\_ips

You mean hostvars[groups[‘localhost’]|first.new\_ips  
Doesn’t work!

{{hostvars[groups[‘localhost’].new\_ips.results.stdout}}  
Gives the following error: One or more undefined variables: ‘dict object’ has no attribute ‘localhost’

You know what- I answered your title, not your question. If you don't  
want to have to try and persist things between plays, you might have  
more luck with something like this:

- hosts: myhosts  
&nbsp;&nbsp;&nbsp;tasks:  
&nbsp;&nbsp;&nbsp;- shell: echo things  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;local\_action: true  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;register: new\_ips  
&nbsp;&nbsp;&nbsp;- shell: echo other things {{new\_ips}}

but there's nothing in your example that seems to necessitate anything  
that you're doing.

haha…okay! I did not want to post my whole playbook as it might get confusing. I really do appreciate your help though. Here is a sizeable chunk of the playbook which might make things easy (or difficult) to understand 🙂
