It seems there are more Ajax tools popping up all over the place, but I gotta say, I like this one. I’m a regular ‘whois’ user at whois.org, and I’m pretty impressed with the Ajax offering, in particular with speed of information retrieval.
You simply enter your domain name (no need to click any buttons) and it searches on the fly, returning your results if the domain is available or not. If it is taken, you are given the option to perform a ‘whois’ with instant results, or alternatively backorder the domain for when it becomes available.
I gotta say… thats one useful tool to have!
