Host Names DHCP server

Animan

Greetings

Device ZyXEL EMG2926
In the client list > DHCP server, some host names are displayed or replaced by an asterisk " * "

What is the reason?

Thank you

Not all devices give out what they are by name

Hi
because the router can not identify the name from the mac address, or some device don't provide the info to router.
