I've had this question on my mind for a time now, I've been wondering: how can I be completly sure that a domain is mine? it's mine just because I've the pass and user name in the hosting it's registered on, or the domain is not mine but of the hosting's??
Pardon my english, and thanks in advance for your responses.
That depends on the hosting company. If you have bought the domain name, and they handle this properly, the domain name should be registered in your name. There are some companies that doesn't handle it correctly and instead registers the domain name to themselves.
You can check the registration information using a whois service, like www.networksolutions.com/whois/.
Even if you aren't listed as registrar for your domain name, and the company refuses to correct this, it's possible to get it back by contacting the registration authority. My domain name guffa.com was registered on a company that went out of business, but I managed to get it back by sending some forms to Network Solutions, who made an investigation and then changed the registrar to be me.
