How to Setup Dynamic DNS (DDNS) using Kea and Bind on Debian or Ubuntu

In this video we show you how to setup Dynamic DNS (DDNS) using the Kea DHCP server and Bind 9 DNS server on Debian or Ubuntu

Having a DHCP server is great because it gives you a plug and play network

The only problem is when you want to connect to a computer by its name

And that's because traditional DNS relies on the IP addresses staying the same

Now you could reserve an IP address in DHCP and then you don't have to keep updating DNS, but it's still extra work and it isn't really scalable

Alternatively you can set up Dynamic DNS which involves the DHCP server telling the DNS server about IP allocations and the DNS server then updating its own records

I struggled off and on for days trying to figure this out. I was 95% of the way there, but I’m not sure I ever would have figured out that last 5% without this tutorial.

Thanks for your great videos on KEA and Bind9. I'm really thankful and it helped me to understand a lot about DNS and DHCP! I wanted to try Stork, the web-frontend from ISC but i can't get it to fetch the statistics from the DHCP and the DNS Servers. I think the "problem" is the tsig-key but i can't find a working manual to add the tsig-key to Stork. It would be realy great if you could add a new video to your great playlist.

Thanks David, currently learning docker + cloudflare tunnels with subnet and email authentication (so I can homelab from work), just bookmarked for later, much appreciated.

Just GREAT!
I do not know how much days I tried to setup DDNS, failing and failing.
And this tutorial - everything fine.
However, just an idea.
DNS with a deeper dive (setting up such things as subdomains) is something realy "confusing" for me.
An tutorial about DNS in debth would help a lot people.
Christian.

Hi David, will there be a level 2 video of this? Dual stack (IPv4 and IPv6)

I configured a secondary DNS on an extra LXC with your videos. But after this DDNS video, the bind service on the secondary says: "failed while receiving responses: REFUSED". My guess is that i need another key -> ns1-ns2.key but i can't get it work. Can you point me the direction?
