If you want to stop using a domain name, there are a few steps you need to take. First, you’ll need to find the registrar that owns the domain name. Once you have their contact information, you can request that they unregister the domain name for you. If the registrar doesn’t agree to unregister the domain name for you, then you can contact the domain name’s owner and ask them to do it. If the owner refuses or can’t be found, then you may have to take legal action to get the domain name unregistered. ..
