It is quite often coupled with dhcp to provide dynamic network services that have hostnames follow the appropriate machines around. To do it securely, you need to first create a secret key. For every zone you want to allow dynamic updates (for this specific key), you need to add an That's all we have to do.
This secret key will be used to authenticate our dns update clients with the dns server. Create the key as such: No, that is not the key I use. Restart named and you should be able to push updates dynamically to the dns server.
#tl;dr version: You are running Synology Diskstation DNS and DHCP services and you want dynamic DHCP reservations to update DNS immediately.
#Background Synology Diskstation has an embedded DNS server that can be enabled for your network.
Luckily for us, there's a tool that'll do that for us. No, you shouldn't use that key for your server ;) The last token in that file is the key (N8Hk...). nsupdate is the tool we'll be using to test if we have setup the server correctly.
That tool is called is a tool to create dnssec keys, much like ssh-keygen creates ssh keys. nsupdate takes commands like nslookup does, if run without arguments: Worst case, run named with a high debug level.
A setting to enable/disable DNS update support completely.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.Under the covers, they use DHCP to get an available IP address from your DHCP server.This does the standard thing of resolving hostnames to IP addresses.So, lets say you have a VMware ESXi server on your local network. Only the DNS server needs to remember the IP address. Synology diskstation also has a DHCP server that you can use to dynamically assign IP addreses to hosts on your network.Specifically, it will push forward (A) and reverse (PTR) lookup entries.
