The reason you are seeing the above is that when a device makes a DHCP request 
it
includes as part of the request its "hostname".  Your router, like most routers,
records this information in its list of "DHCP Clients".  That information is not
magically inserted into any DNS server.

I downloaded the User Manual for the router and there is no indication that it
actually runs a "DNS Server".  Like many routers, it simply acts as a 
"resolver" and
"cache" for DNS entries.  It actually passes the DNS queries to another server 
that
you've configured.  Typically, that would be the DNS server of your ISP.

As already pointed out, that would be either an Android Phone or Android Tablet.

I use a Synology RT2600ac router which has an add-on DNS Server package.  It 
will
allow you to make local DNS entries. 

I actually don't use that package since I run a DNS server on my Fedora system. 
 I
then use the feature in my router, which yours has as well, to lock a MAC 
Address to
a DHCP supplied IP address.  And I make the appropriate entries in the DNS 
server. 
Then, depending on what I'm doing, the devices on my network will either query 
the
router's DNS or my Fedora DNS.   (A bit complex since I use proxy DNS services 
from
my VPN provider to easily access non-local video content)

As I said, I don't think your router runs a real DNS server.  See my comments 
above.

I like my Synology Router.
