Websites for testing if a resolver is DNSSEC-enabled

Normally, to test if a resolver is DNSSEC-enabled or not, IT people will  use "dig +dnssec"  followed by something and then verify that the message has the AD (Authenticated Data) set.  Instead of using such command line testing,  I am a bit lucky to find two webistes for performing the same task:

1.  http://dnssec-or-not.net/

2.  http://dnssectest.sidn.nl/

The screen dumps below are interesting.
