You cannot do this in XML Schema, because it doesn't have a mechanism to
say that the content/type of one part of a document affects the
content/type of another part. (Often described as co-occurrence
constraints, and not possible in XSD.) There are other schema languages
that let you do that kind of thing. But even then you will have a problem
because they typically only do regular-expression kinds of constraints,
and doing that kind of validation with a set of regexps might not even be
possible.
And then, finally, you almost definitely want CIDR not old-fashioned
network classes anyway. :)
