Hi Vladimir, The DHCPv4 domain-name option (15) isn't meant for use with ddns. It is a search domain that the client should use when performing name resolution. See: https://www.rfc-editor.org/rfc/rfc2132#section-3.17
You can set ddns-qualifying-suffix at the global, shared-network and subnet level. In a host reservation, you can use the "hostname" parameter to specify a FQDN to send to the client and for use in DDNS.
