Hello friend, I would like to know names of the free tool which gives instant information, that a domain is available or not. Which tool you mostly use?
www.instantdomainsearch.com
You can even get a discount for clicking through their link to buy a domain on godaddy's site.
HOS
For bulk searches I've mostly used name.com to date.
For this, you have to check domain registrar, how can I know what is in your mind so that I would tell that this domain is available to register?
