First, thanks for the answers.
Sorry, the question was: why?
I know, but the domain expired more than two months ago because i didn't need it anymore. It was the website for a small community with users living mainly in my town, and it no longer exists.
Now with some friends, we decided to bring the site back to life.
For me it would be very practical to register the domain with dreamhost, because i already have other domains registered and I could manage averithing from the same panel.
Aniway only one registrar said that the domain is free, but it was an error. I checked with oteher registrars and the domain results to be in status "pendingDelete".
Can i wait for some time and let the domain definitely expire, or is better to register back with the old registrar and then transfer the domain?
I don't think that anyone would claim the domain because it isn't of any particular commercial interest.
