Dhcp server updating dns records
(Obtained as is from: The steps in this post shows how to configure the DHCP server to automatically update the DNS records when giving out a new lease to a client computer.
Before continuing These steps assumes that you already have a working copy of dhcp3-server and bind9 installed.
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.
If you don’t have that I suggest that you first read my two other posts on how to install them: Setting up a DNS for the local network on the Ubuntu Hardy Heron server Setting up a DHCP server on Ubuntu Hardy Heron Step by step instructions Apparently the Ubuntu server is installed with an App Armor profile that prevents bind to write to the /etc/bind directory.
The default profile suggests that these files should be put in /var/lib/bind.
This means you can power up a new laptop, ipad, or guest VM on your network and it will be able to use the network without configuring anything.
#Background Synology Diskstation has an embedded DNS server that can be enabled for your network.
This does the standard thing of resolving hostnames to IP addresses.
Scripts that help with Synology Diskstation maintenance ##Why do I need this?
#tl;dr version: You are running Synology Diskstation DNS and DHCP services and you want dynamic DHCP reservations to update DNS immediately.Under the covers, they use DHCP to get an available IP address from your DHCP server.
