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
