This site is Class A no-www compliant 2006 January 24
A while back I made a blog reference to www. is deprecated movement at 
. This came up in the #lug/ip IRC channel today, so I decided to test my compliance status. ecorrado.us is Class A compliant. According to no-www.org, Class A “is the most common no-www compliance level. With class A domains, example.net and www.example.net are both valid methods of reaching this website. Many servers default to this.” Here are the results of a test on ecorrado.us:
Checking ecorrado.us and www.ecorrado.us DNS records
www.ecorrado.us is a valid hostname
ecorrado.us is a valid hostname
Testing www.ecorrado.us for HTTP access
Port 80 access successful
Testing www.ecorrado.us for redirect to ecorrado.us
www.ecorrado.us does not redirect to ecorrado.us.
Testing ecorrado.us for HTTP access
Port 80 access successful
Testing ecorrado.us for redirect to www.ecorrado.us.
ecorrado.us does not redirect to www.ecorrado.us.
No redirection detected... testing to see if ecorrado.us matches www.ecorrado.us.
ecorrado.us HTML matches www.ecorrado.us.

Domain qualifies as Class A
the arguments against the www subdomain are flawed. Mail systems have DNS records — MX records, that you can use to tell mail software where your mail exchange is. There are no universally accepted DNS records to tell web software where to talk to a web server. There are SRV records, but most web browsers don’t bother checking.
