How to get domain name free

well cant say if you can get domain name for free but we are offering free domain name with our shared hosting plan.

i think .com domain name is not free . .com is paid domain name. but .tk is free domain name

You can not have a .com for free because it has an annual or 6 month fee.

can we actually get a .com domain absolutely free?
