MySQL has dotted IP string to integer (and vice versa)  conversion 
functions.  You'd use them in queries like:

insert into  mytable set IPaddress = funcName('');
select funcName(IPaddress) as strIPaddress, IPaddress as intIPaddress 
from mytable;

I suspect you posted to the list before attempting to the functions in 
the online documentation so I'll  simply confirm they exist and leave 
you to: Do Your Own Research by Reading The Fine Manual.
