Other Alphabets

Westerners often forget that there are a decent number of alphabets in use that don't use Latin characters.  In 2009, internationalized domain names that use non-Latin characters were approved, allowing for a much broader array of characters from which to build domain names.  The non-Latin characters are translated for our "Latin-only" DNS system using a schema known as "Punycode".  What does this mean for analysts?  There are a lot more domain names in use on our network than we might realize.  Unfortunately, because of this, some of our "Latin-centric" analytical methods may miss certain traffic that we may want to inspect more closely.  It's something to be aware of.  Don't be a "Latin-centric" analyst.  :-)
