You may have to roll your own like:
def before_save find(:all, :conditions => ['ip_address = ?', convert_to_int(self.ip_address)]).empty? end

just a note, convert_to_int is simply a facade that you should replace with whatever method you are using to do the conversion, I assume IPAddr#to_i, but none-the-less, you get the gist of it.

yep, or you could clean it up even more by eliminating the unnecessary instance variable:
def validate # check if the ip_address is unique unless Machine.find(:all, :conditions => ['ip_address = ? and id <> ?', IPAddress.to_int(self.ip_address), self.id]).empty? errors.add :ip_address, "is already taken" end end
However, both will work, this one just uses a tad less memory. Glad it worked for ya.
