I have a problem to get Hostnames registered in DNS (Windows AD DNS-Server) when they request a IPV6 (NA). While IPV4 gets fine i can see in syslog an “added reverse and added forward mapping” it doesnt get shown for ipv6 linux clients but Windows clients does via the dhcp server (shown in syslog).
i have the following config:
dhclient6.conf
interface "eth0" {
send fqdn.fqdn "debtemp.ad.example.com.";
send fqdn.encoded on;
send fqdn.server-update off;
}
dhcpd6.conf
default-lease-time 2592000;
preferred-lifetime 604800;
option dhcp-renewal-time 3600;
option dhcp-rebinding-time 7200;
