Getting Info on a Domain

Maybe I'm reinventing the wheel, but...

I have found an useful utility for easily seeing and collecting informations about a domain.

DomainHostingView
http://www.nirsoft.net/utils/domain_hosting_view.html

It's a "no install" program for Windows.

"The information displayed by the report of DomainHostingView includes:
the hosting company or data center that hosts the Web server, mail server, and domain name server (DNS) of the specified domain,
the created/changed/expire date of the domain, domain owner, domain registrar that registered the domain,
list of all DNS records, and more..."

I find it useful.

I like the service from who.is and domaintools.com including domain holder history.
