There is a domain related to my existing domain. For eg - my domain is abc.com and the domain which I am trying to acquire is abcd.com. I checked the domain availability with name.com and who.is as well, according to both websites the domain expiration date was 28feb, 2012 but till now it is not showing as available. I am totally confused that why it is so? I want to get it before anyone gets it because it is very much similar to my existing business name.

If it is already expired on 28th then why it is still showing as "Taken" ??
