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. > 1. What is the device android-a81a750feb8c4486?

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.

It isn't a fact.
