randomizing , also: randomising BrE

In addition to repeating trials, randomizing the order of trials in an experiment is another example of how scientists can ensure that the variables under consideration are responsible for the effect under consideration.

Open recursive (caching) DNS servers are especially vulnerable to cache poisoning attacks, but Google has implemented several mechanisms to counter these, including one system that wasn't adopted in the IETF because there are some problems with it (randomizing the case in DNS names).
