I've come across devices like this that just don't do lease renewal.
They get a DHCP lease for whatever time the server gives them, but don't
actually renew it. When the lease-time expires, the hostname disappears.
The fix is to tell the dnsmasq DHCP server to give that device an
should do the trick.
