fixed-address6 and ddns-hostname

[winsor at ukrhub.net]

Hello!

I use dhcpd 4.3.1 to manage my ipv6 space. And i need DynDNS support. My config for ddns:

ddns-update-style interim;
ddns-updates on;
allow client-updates;
ddns-domainname "ipv6.mydomain.net.";
ddns-rev-domainname "ip6.arpa.";

Define subnet:
class "winsor_intf" {
        match if ifname="ge-1/0/1:13";
}
subnet6 2001:db8::/48 {
	pool6 {
                range6 2001:db8:3::/64;
                allow members of "winsor_intf";
        }
}
In this configuration ddns is working properly. Logs:
update: info: client updating zone 'ipv6.mydomain.net/IN': adding an RR at 'wpad.ipv6.mydomain.net' AAAA
update: info: client updating zone '8.b.d.1.0.0.2.ip6.arpa/IN': adding an RR at '0.f.4.e.f.6.f.6.9.0.c.c.5.6.5.0.0.0.0.0.3.0.0.0.8.b.d.1.0.0.2.ip6.arpa' PTR

But if I add a configuration for fixed host:
subnet6 2001:db8::/48 {
	pool6 {
                range6 2001:db8:3::/64;
                allow members of "winsor_intf";
		  host wpad {
                        host-identifier option dhcp6.client-id 00:01:00:01:1a:16:60:1e:b4:b5:2f:90:df:13;
                        ddns-hostname "wpad"; #or without ddns-hostname - ddns does not work
                        fixed-address6 2001:db8:3:0::100;
                }
        }
}

dhcpd not send ddns query to bind. please tell me where the error in my configuration and is supported ddns for fixed hosts?
