James wants to know about ICAN and how the internet addresses work. Leo says that ICAN controls the domain naming and uses various registrars to register your domain name. But James doesn't want to pay with a credit card. Can he pay with a money order? Leo says that you'll have to contact the registrar to find out. Paypal works. You could try a visa gift card. Can he create a domain anonymously? Leo says that ICAN wants to tie domains to the owner, but you should be able to make it anonymous to anyone but ICAN.
As for ICAN, the chatroom says that there is https://www.moneyorderdomains.com/.
