You would attempt a zone transfer of the domain, as such:

        $ dig axfr um.
        
        ; <<>> DiG 9.3.2 <<>> axfr um.
        ;; global options:  printcmd
        ; Transfer failed.

As you can see, it doesn't work. Zone transfers are one of those wide
open security holes that have been plugged by the Internet at large for
some time. Generally it's only allowed for secondary name servers.

I sure hope you weren't planning to spam all those unsuspecting Minor
Outlying Islanders.

No, I was attempting to find out how many, if any, subdomains there are for .um.  Since as far as I am aware, all of the U.S. Minor Outlying Islands are uninhabited, there shouldn't be any.  But how do I confirm this?
