Android, first DHCP get a IPv6 link local that i don´t have on my DHCP Server

Hi all.

First, thanks for read this:

The DHCP server is a ipv4 only on a W2019 Server.
My android devices get the ip addres correctly on ipv4, but if check the ip y see my primary dns server is like fe80::250.......,
The DNS2 and DNS3 are my coorect internal dns servers.

but i don´t give it on any dhcp option or similar.

The problematic is that the android devices fails to resolve local dns names......

Any help will be appreciated.
Regards.
