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.

See CERT VU #800113 for information on the DNS cache poisoning vulnerability.
