My point exactly. They will not be controlled. There is no point even
worrying about it.

Without namespaces it would. That was why I was concerned. Mistakenly I
am relieved to hear.

I withdraw my concerns. and will plow ahead with some practical work.
You have lifted a great concern from my mind. (01)

The web is tightly managed. I can not just make up IP addresses. I have
had one of my Class C address blocks mistakenly reallocated once which
cut off European access to our sites until I contacted the European
authority and got them to fix a typing error. (02)
I can make up domain names but I can only use them inside my network.
Otherwise I have to register them and this process is tightly
controlled. I can only get new names that are not already given out. (03)
Tight but decentralized. (04)
