Recenlty I get a free domain from co.cc. It is totally free. But I am affraid that after one year or some time later will I have to pay for renew my domain?

Are there any experienced domain guru? Give me answer!

You should read the rules of the company you got it from.

I tried register.com free offer and it is really free!

I don't believe it's free. no such thing as free domain name.

Is co.cc like .tk? Or any of those shortening URL websites? If so, then I don't see why it wouldn't stay free. .tk has stayed true to their word for quite some time now, though I think you can pay with them to remove their advertisement. At least that's how it was several years ago when I used them for a gaming website.

You should buy TLD rather these kind of free domains.

I hope .co.cc is a sub domain so it would not charge anything

I don't like free domains such as .co.cc. Not only do I believe they look unprofessional I sometimes don't like to think that what I'm using is free and I'm bound to some rules which may determine something I don't want to do or abide by.

Read through the Terms & Conditions. If they say that you have to pay after the first year, then cancel now or before then. Or even better, get a paid domain name like .com or .co.uk.

I use .co.nr, it works well and is very 100% free

Some of domains are free, totaly free. But there are always some terms of use.There is many hosting companys that will give you up to 3 free domains if you take hosting with them.

Microsoft offers free domain registration to small businesses. I have seen this work before! The problem is that they will have control of your domain and dns servers. Most people giving away free domains will do this to you.
