Guest ~BD~ Posted August 2, 2008 Posted August 2, 2008 Re: DNS Randomness Test 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.

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
