I have a few devices that dont give out host names. I assumed that dhcp reservation works based on mac address only, but apparently it needs the correct host name as well.

hardware version: b1
Firmware version: 2.02

example
DHCP Client List
--   192.168.0.4    1c:5a:3e:fb:8a:e76   23 Hours 12 Minutes

dhcp reservation
tv1  192.168.0.120 1c:5a:3e:fb:8a:e7

-- seems to be generic for "I don't know what the hostname is"
The mac address belongs to a smart tv.
Intended behavior? Or can I hope for a fix.

and fyi dhcp reservation works for other devices that give out correct hostnames.

You can manually change or you should be able to manually change the unknown host name to something intuitive. This does happen on D-Link routers. I just change the name to something I can identify the device with.

Here's a work around that hope helps you as it did me. Here's what I was trying to do. I wanted to reserve a static ip for my HikVision Network DVR and it seemed always return the host name as -- . My older DLinks would happily map a set IP with the devices MAC but this model seems to additionally expect a valid hostname.

Instead of reserving an IP from the DLink Router configuration, I set my DVR to use a static IP which was outside the router's DHCP range. I set mine to 192.168.0.250 and my router's DHCP range was 2~199. (Apparently you shouldn't set something within your DHCP range to avoid conflicts) And that's it !

Now, after every reboot, the same IP is assigned to my DVR and my port forwards work nicely too

You can also reserve an IP address on the router as well for devices, which is preferred. Also you can give a host name as well for ease of identification of the device. Some devices have hostname input values as well.
