Noob question. Fair warning. I am trying to understand what the "Active Host Name" and "Client ID" do, and if they can be renamed, when the IP address is made static. (The wiki entries are unhelpful, to me.) Sometimes I see blank entries, sometimes I see multiple entries (a computer that is both wired and wireless connect to the router), and sometimes it will not pick up a clients friendly name (e.g. Firestick TV or android phone) and place under either of these two categories. Client ID is supposed to follow a naming convention, but I'm afraid to change it (or the Active Host Name), if it will break NAT, etc.
What can, or can't I do?
