Value not persistent in dhcp-server settings

I found out that the value “DNS Domain” disappears after a reboot. Another issue is that the value “Domain” will replace the “DNS Domain” value. You will see that if you exit winbox, and then reconnect to your router.

RouterOS = 4.16
Platform= X86

DNS domain and domain are the same settings.
It will be fixed in the next version, where domain will be present only.

Thanks! I wasn’t sure about that, I thought that “Domain” was related to Windows Domain.

Yes, it is correct. Domain is applied for Windows domain.
