Dynamic DNS DDNS service on ISPconfig

Hi all,
I've searched around for this, here and more widely, but not finding any recent helpful replies.
So, can someone tell me what's the best way to run a DDNS server to allow A records to be updated, with an ISPconfig setup?
By "best" I mean, easy to set up, reliable (low/no maintenance), secure, and no clash with ISPconfig.
My server is Ubuntu, and I have existing domains hosted with the server, at Linode.

Thanks for any advice!

I'd suggest you simply use cname instead of an A record then. My ISPConfig servers at home rely on it too.
