Any ideas for running this script for a IP range like 192.168.88.80-192.168.88.89?

I'will try this for you, the problem is I do not use this IP Range on my Router !
My Question to you, You use dynamic or static IP leases ???
And why do you need this only for 9 IP addresses ???

I do make-static lease, I want to add them to an address list for mangle rules for queues. I have my Business PC in this range, another has Gaming Console, another TV/DVR, etc..

I had already made changes to your original script to put the addresses in one list and I added host-name to the comments and log output!

@BrasDeutscher I finally figured it out I do appreciate your willingness to help!

Very good!

thanks, i add some code to the script for my simple queue Qos on target device in my home network.
Create task scheduler that run the script every 15 min.
