HOSTNAME doesn't display in Traffic Graph

    For other hosts (like servers on the LAN that have a static IP), if their name-to-address and address-to-name are stored in a DSN server somewhere then;
    Add a domain override to send the reverse-lookup requests to  that DNS server, like rows 3 and 4 in the attached screenshot. (rows 1 and 2 are sending real domains like and
    For other unknown IPs, you can add a Host Overrides entry specifying the name and IP. Then the DNS Forwarder can do both forward and reverse lookup on that data.
