<br>&nbsp;&nbsp; The only improvement I can suggest for your rule is to not use collect if you are checking for the non-existance of and object (size == 0). &quot;not&quot; does the job and is much lighter from a performance perspective:<div class="Ih2E3d">

<br>This works fine, but I would like to constrain the IPAddress&#39;s usage within the collect, as opposed to joining.<br><br>Anyone know if this is possible?<br><br>thanks<br><br>dave<br>
