You can get sub domains with .com extension in free. For example you can book your sub domain at weebly.com, webnode.com, wordpress.com etc. If you want to register as a custom domain in future then you register as well here. But you can not book .com custom domain for free. There are some such kind of providers they provide .com domain in free for first year but then after when you renew such domain they charge too much money.
You can get a free .com domain name but the only way to do that is buy a web hosting plan that offers a free .com domain.
Either way you have to pay for it one way or another. It is cheap anyway why not just pay for it? Only 10 bucks mate. Get one from killer: http://killerdomains.com.au
I recently received an email from a visitor asking if it was possible for him to create a website without buying a domain name. This article attempts to answer this, and on the way, tries to clarify a misunderstanding about creating websites that usually accompanies such a question.
Hey dear, it is not possible, if you want to make a website, you have to purchase a domain and web hosting.
