Implicit in my reply was that assumption. It is what I am accustomed to,
even though my own ISP offers the facility you describe. Thank you for
pointing out how different ISPs allocate addresses. I will try to
remember that a router may not have a routeable IP address. Given a
choice of ISPs, I'd not choose one who imposes what you describe.
