That is because the DHCP server does not add the hostname into DNS. The network accounting report does a reverse lookup using the DNS servers you specify. No match, doesn't resolve.
I don't believe the Astaro DHCP server registers hostnames of clients in any DNS server, including internal ones. Microsoft's DNS Server in Windows Server 2000 and up does, if you're using Microsoft's DHCP server... and, of course, there are open-source solutions that will do likewise.
