What if the domain name I want is taken?
There are millions of domain name extensions and you are likely to find a domain name available but if the domain name of your choice is already owned by someone else, then you will have to find a new one or try to talk to the owner and see if it’s possible to buy from them.
Some domain registrar also provides additional services on this and also some domain registrar will also have domain sales market to sell already registered or expiring domains.
