Right. In case you haven't found it (or something similar), there's an online MySQL manual with a function reference here: http://dev.mysql.com/doc/refman/5.0/en/functions.html

Also, could you explain why the original values in the column do not appear as UNHEX'd? It seems that the only two that appear to be UNHEX'd are #s 2 and 9 in the column.

To be honest, I'm not an SQL expert or anything, but I like figuring out stuff like that. So I don't know the answer for sure, but my guess would be this: that column is just 4 bytes (one representing each section of an ip address), and whatever program you use to display that column (phpMyAdmin or whatever) displays it as a 4 character text string if all the bytes in the string happen to represent printable characters, otherwise it shows it as hexadecimal.
