Special-Use Domain 'home.arpa.'

[techlists at phpcoderusa.com]

Hi,

As you know I am building a "home office" lab for PHP development and 
testing.  I was not satisfied with the research I completed on 
"non-routeable" domains for a private network made up of "non-routeable" 
domains.

In the distant past I used to use .dev for the TLD.  From what I am 
reading this is not a good idea.

According to https://www.rfc-editor.org/rfc/rfc8375.html one should use 
"home.arpa.".  They add a period to the end which I assume is the DNS 
domain name stop character when used in zone files.  Any thoughts?

I will not be using DNS.  My needs are so simple I will be adding the IP 
and domain name in my host file, at least for now.

I've read a lot about this subject.  Some say to use a registered domain 
with a subdomain that is on a private IP. I really do not want to 
commingle public and private assets on the same domain.

Any feedback is much appreciated!!

Thanks!!
Keith
