Or use a combination of both approaches (separate second level domain and
distinct subdomains in a shared public/private domain tree) if that fits
your needs. The different aspects are for distinct needs. At work, for
instance, we use a completely separate second level domain tree for many of
our primary Active Directory forests and their constituent domains. We use
private subdomain trees under our public second level domain for many other
things. The appropriate internal/external boundaries require some thought
and ongoing management, but it's not especially difficult.
