DNSreport.com is a great tool for quickly analyzing a domain name registration and setup.
I have personally used it for many years, and still use it almost daily to check various domain names etc.
However about a year ago DNSreport.com became a paid service.
I perfectly understand that they need to finance their servers etc. and I am happy to pay the membership fee, especially since I use it as much as I do.
But a lot of people were unhappy about this because they didn't use the service enough to justify paying for a membership, and there weren't any good alternatives around.
Simple DNS Plus users have often asked us to provide a similar service or tool - or if we knew of any alternatives.
We do provide several free on-line DNS diagnostics tools - see http://www.simpledns.com/addons.aspx#online
But nothing as comprehensive as DNSreport.com.
