I could not find anywhere that gave the MEANING of the acronym for this fucntion, but i believe that is stands for AddressTONumber and NumberTOAddress Ok, i’m sorry, one more post.

Char (and varchar, if i remember) is (1*length)+1 bytes for Ascii, and (3*length)+1 bytes for UTF-8, sorry. I’m sorry i need to correct myself.

It still has to store the terminator, because you can use that datatype to represent things that may just be CLOSE to the same length, for greater speed. As for this post, this is a great function, and it really does decrease storage size and increase speed to store ips this way. I found this post while googling the MEANING of the name "ATON". I'm sure it stands for something, so i just got a wile hair to search it out..... Also, the comment just above mine is spam. You should remove it.

CHAR(15) will take 15 bytes if on non-unicode charset (such as ascii or latin1), or 45 bytes if on utf8 VARCHAR(15) will take 16 bytes on charsets such as ascii or latin1. To support Josh’s comment:

This data was taken from phpmyadmin's space data and row size. I agree with your comments of an INT taking 4 bytes and a VARCHAR(15) taking 16 bytes, I will update the original post so this is made aware to other readers.

Also, I'm not sure about the other types. A VARCHAR(15) should take 16 bytes at most (0-15 bytes for the data plus 1 byte that represents the length of the string) and a CHAR(15) should take 15 bytes, assuming the character set encodes characters on a single byte. http://dev.mysql.com/doc/refman/5.1/en/storage-requirements.html Small correction: as per MySQL’s manual, an INT (UNSIGNED or not) takes 4 bytes, not 7.
