yes it is in the HEAD, but currently it only works if the last byte of
your gws' ip address is less than 128. this is due to ser db interface,
which doesn't seem to support unsigned ints or then i don't know how to
use it.
Try this,
http://dev.mysql.com/doc/mysql/en/numeric-types.html
When you create the table field, you can use attribute "unsigned".
