Dns not updating from dhcp 2016
This script does that and it now does it without overwriting static DNS entries in the range of .
As of 2014-10-20 Synology Diskstation DSM cannot do this from the GUI.DDNS is most useful when it is teamed with a DHCP server; as the DHCP server hands out IP addresses to clients, it can send a DDNS update immediately.This allows mobile or transient clients to keep a stable hostname and to always be found through a DNS lookup.It is unlikely that other devices on the network want to communicate with the laptop using a hostname.This becomes more of an issue when you have more devices and servers running on your network.2015-08-13 A new script is available to start this service each time the synology diskstation boots up.
You no longer need to have any Task Scheduler items when using this script 2015-08-13 Updated documentation 2015-08-13 Updated file path in scripts to match a more generic location of the admin account directory.
The DNS server knows nothing about this hostname to IP address assignment.
This means that no other host on the network will be able to refer to the laptop if they only know the hostname.
For example, when you power on your laptop, the laptop will essentially say something like this: "Hello, my hostname is and I need an available IP address".
The DHCP server will gladly assign an unused IP address, but that is where things end.

DNS will not be updated from new reservations until this script is started again.
