Because the Internet Census 2012 data was collected
with the use of a botnet and scans done without permission, there are
some ethical issues that surround the use of this data set in research.
With the internet census, and any other data set obtained in what may be
viewed an illegitimate manner, researchers must decide if they have the
right to use the information.
