Hello there,
It has been a while since I posted.
I decided to do DDNS on my home network using Bind9 and the ISC DHCP server.
As always you test on a lab first.
I have EVE-NG and I was running a lab with DDNS and IPV6.
I used Fedora core so to make it like my network I replaced the server with Ubuntu 20.04.
However, I run into an interesting problem.
