I hope this isn't too much info overload.
First, let me say I am learning; I am not an expert, nor do I maintain anything of importance other than my home network.
I need help understanding why I am getting these and how to fix them along with best practices.
My FQDN is not real. From what I read and have been told I could use any name, as long as it followed conventional naming, I chose mylan.lan
Thanks in advance for your help and suggestions.
Ed....
These are the errors I am getting when I start named. Named.conf is below.

It's more appropriate than asking for help and forcing us,
by not including significant information, to guess what
your problem might be. 8-)
OTOH, it's probably not appropriate to send a gazillion
files. Do try to send only "files needed in order to help".
