Forest root domain nameing

[JDonahou]

When creating a forest root, can the domain name appear to
be a sub domain of another, yet be it's own forest root.

For example: XYZ company has a web presence of www.XYZ.com.
Then you want to configure their internal network as
corp.XYZ.com. There will be no direct connections,
logically or physically with XYZ.com.

So the question is can a root domain appear to be a sub
domain, even though it truly isn't?

Assuming you mean can it be a "three (or more) tag" name: Yes.

yourdept.yourplace.com CAN be the forest root domain.
Perfectly fine, it would be ODD if you intend to add yourPlace.com
in the future.

Technically, this should work as a separate "tree" but I wouldn't
guarantee the tools will actually let you do it.

For example: XYZ company has a web presence of www.XYZ.com.
Then you want to configure their internal network as
corp.XYZ.com. There will be no direct connections,
logically or physically with XYZ.com.

Perfectly normal and one of the better choices.

Yes.

You really aren't even asking what you think you are asking
(or what your words indicate): In DNS, the root is named "."
(spoken as "DOT"), and it is even a bad idea to make a domain
forest start at even one tag (don't do that) or "top level domain"
, e.g., corpName, or companyName.

Always start at LEAST two below the DNS root (domain.com etc.),
or more if you prefer.
