| Me neither, Dave. I understood me perfectly. :o)

 

Well he's a MVP in "Windows Server - Directory Services" not in "Security".

Only if you have no idea how to check the link or use an operating

system.

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
