Note, however, that the DHCP protocol itself provides no security, and that clients can therefore provide information to the DHCP server which the DHCP server will then use in its updates, with the constraints described previously.

The DNS server must be configured to allow updates for any zone that the DHCP server will be updating.

Probing the DNS servers via dig returns no records for the hostname.

3.1 Edit /etc/bind/local: # # Make sure to change the ddns update style to interim: ddns-update-style interim; ignore client-updates; # Overwrite client configured FQHNs ddns-domainname ""; ddns-rev-domainname ""; # option definitions common to all supported networks... subnet 192.168.0.0 netmask 255.255.255.0 The configuration files now contains our secret key. We also have to give the DHCP-server the permission to read and write it’s own file.

We have a set of Windows 2012R2 domain controllers which provide DNS and DHCP service for the network.

I have an Ubuntu 14.04 server which is getting addresses via DHCP. In the Windows DHCP server, I have converted the lease to a reservation.

When either type of client (static or DHCP client) initiates an A record update with its authoritative DNS server, it will first start by performing an SOA query for the FQDN of the client in question: The client then receives a response from the authoritative DNS server containing information about the server that is to process the dynamic update.

From there, the client continues communicating with the primary DNS server that accepted the A record update.Have you ticked the dox in DNS properties on the server role that is listed as "Dynamically update DNS A and PTR records for DHCP client that do not request updated (for example, clients running Windows NT 4.0)?ddns-updates on; ddns-update-style standard; update-conflict-detection false; allow client-updates; ddns-domainname "local.domain.com"; ddns-rev-domainname ""; update-static-leases true; default-lease-time 7200; max-lease-time 7200; authoritative; [...] Whenever a client gets a new IP from the DHCP, the DNS registration works perfectly.Aug 11 NIKKI named[5680]: zone 'mydomain.lan' allows updates by IP address, which is insecure You need to define an update key and configure it in both and The manpage for gives an example and, I believe, the standard contains a commented example.Statically-set clients (static clients) that perform dynamic updates will send updates for both its A record (forward lookup record) and its PTR record (reverse lookup record) to the authoritative DNS server.
