: Purchase domain and web-hosting from different company I know that it is possible to purchase domain from one company and web-hosting from other, but I have never done that yet. Its first time

@Hamaas447

But how the company B knows that I am real owner of this domain.


Company B hosting company is not tied at all to domain names, Company A holds the registration and DNS settings.


What If someone already purchased web-hosting for this domain in company B.


Domains can only be registered for one company/individual, when you purchase that domain it is your for the remainder of the registration term.


It means that I would not be able then to purchase webhosting from
this company for my domain? Or how does it work?


You can purchase hosting from any company that you which, you can even host your setting from own computer if you have a static IP address.

Domains

When you purchase a domain, it gets registered with that company(the domain registrar) that company sends all the domains they have registered to the domain name registries.

DNS settings

Keeping it simple DNS settings routes visitors from your domain name to your Server.

Hosting

Keeping it they provide servers to host your site So go to your domain registrar and change the DNS settings to point to your hosting server on the other company.

Like you've mentioned, the hosting and the domain are two completely separate things.

In your case, Company B doesn't care. It just provides the storage and the environment. When you point your domain to your hosting (by changing the name servers), you need to go to your hosting configuration (most often in the form of a control panel such as CPanel) and assign the domain to point to a folder in your hosting account. That's it.

You do raise a good point though - what if you're using a shared hosting and there are other people on the same server? Can someone maybe hijack a subdomain of yours that you haven't yet assigned to your account?

Sometimes the answer is yes. This can happen if you create a wildcard A record for your domain so that *.yourdomain.tld points to your host's IP address. Now it's up to the control panel to allow or forbid that someone else to perform that action - you can't be certain that the panel will tell them "Uh-oh, looks like you're trying to point another client's domain to your folder".

And let's look at one final case. Let's assume that you and I are used the same shared hosting provider and somehow ended up on the same server. I used to own mydomain.com, and it's pointed to a folder under my hosting account. But it has expired and you bought it, and now you want it to point to your folder. That's when an unexpected result can occur (meaning it could point to my folder again while you're the owner of the domain), but you can always poke the support, and I'm sure they would assist you. And the chances for that are extremely slim, as you can imagine.
