If you change namespace, consider using a subdomain of that namespace
for stuff behind your security border, if possible also use split-dns=20
to enable you to have "hidden resources" inside. This split-dns will
also allow you to use 1918-addresses inside without exposing them to Inte=
rnet

You might find licenced products that have licenses with embedded domain =
names. These
has to be renewed ( or you should have a zone where these mahnines may li=
ve until
licensing issues has been resolved)
