This was my result:
DNS Resolver(s) Tested:
1.. 195.93.61.21 (dns-frr01.proxy.aol.com) appears to have GREAT source
port randomness and GREAT transaction ID randomness.
Test time: 2008-08-02 07:42:41 UTC



So AOL isn't *all* bad, eh? <wink>

Ahhh - but wait!

I've tried again today - but this time I didn't use my AOL browser, simply
Internet Explorer.This was the result:
DNS Resolver(s) Tested:
1.. 4.68.25.1 appears to have GOOD source port randomness and GREAT
transaction ID randomness.
2.. 4.68.25.3 appears to have GOOD source port randomness and GREAT
transaction ID randomness.
Test time: 2008-08-05 17:49:47 UTC

Note that standard deviation is usually, but not always, a good indicator of
randomness. Your brain is a better detector of randomness, so be sure to
take a look at the scatter plots below. If you see patterns (such as
straight lines), the values are probably less random than reported.

******************************

Please will someone explain why my IP address is so different, just because
I used a different browser for the check? TIA

Dave
