As there are less and less domain (.com) everyone is trying to get a .com. Why, it is because if your did a website that is successful with a .net, don’t you think some of the user will end up remembering .com instead and the owner of .com will get the benefit. Although .org is slightly different because is not a norm to register .org for personal domain.
Here is some website that could help your locate the closest or your exact domain.
There is this “Name Spinner” features that jumbles up all the letter you typed into the search box and come out with a list of domain, it shows .com .net .org .us .biz. All domain will be shown indicating if it is registered, parked, dropping, or open for registration. Although there is limited function for new user but it is still useful.
Typing http://www.whois.sc/yourdomain.com [without the www] will actually shows information about the domain. I shows things like expiry day, expiration date, person that is own the domain with information, nameserver and hosting ip. All this are quite useful, as I use them quite often.
Another website for domain is http://www.justdropped.com
I usually use this website to find domain that are dropped recently. Because it is a used domain, you may still have some alexa rankings, some visitors and also some search engine links already. As there are thousands and thousands of links dropping everyday, finding a good ones is not that easy, but with this website, it is much easier than before. But you may want to check out the Website History to make sure that it is not some nasty website in the past.
Is another whois website, but the difference is that you can whois the ip and shows what domain is hosted within the hosting company. This is useful to check out a hosting company before you join it.
for .my server http://whois.mynic.net.my – To check informaiton on Malaysian Domain.
Happy Shopping for domain!
