They get configured though front panels, touch screens, usb
connections, over the network using mDNS for initial discovery,
usinge a games connector and the TV screen, etc. There are lots
of way to do this. This is a solved problem as people have been
providing devices with names for about as long as the devices have
existed.
The only difference is that they give the device a fully qualified
name instead of a unqualified name.
They use TSIG to authenticate the UPDATES to the forward zone which
is probably what your DHCP server is using today to authenticate
the updates it sends and one of the methods DynDNS supports to
update the zones it serves.
