Block multiple IP addresses

Is there a wildcard I can use to block multiple IP addresses from my Guestbook? I tried CIDR notation but it didn't work

This feature has not been implemented in the current version of the guestbook. I have added it to the guestbook wish list HERE for future versions of the guestbook.

Thanks Pete. I'm sure you are aware image verification is no longer stopping the spambots and I may have to shut down my Guestbook.

We actually have Recaptcha as a replacement for it. I will let you know when it is done.
