Well, as from what I know, yes. There might be a couple sites that give it for free, but I am not 100% sure they are safe sites. If you want it for free there are websites that allow you to have a free domain with the website you would like to sign up with, but they will be either a subdomain or they will make it .com/yoursite. Then if you feel like you can pay for it, they allow you to upgrade. There are other websites too, that hold competitions for a free domain. Overall, the safe webhosts require you to pay (that's what I had to do) but the websites that give free domains, I am not 100% sure on them if they are phishing, scamming or anything.
