How can I fix these problems that dnsstuff.com reports my server has Took off 8 points for having no glue at a parent server [adds 2 extra packets to lookup]. Took off 10 points since ns1.[HIDDEN].com is an open DNS server (if abused, your DNS may be inaccessible, and over usage could result in slowdowns). Took off 10 points since ns2.[HIDDEN].com is an open DNS server (if abused, your DNS may be inaccessible, and over usage could result in slowdowns).
You can ignore the open DNS messages. As for the glue stuff, have a look here: http://en.wikipedia.org/wiki/Domain_name_system#Circular_Dependencies_and_Glue_Records and contact your ISP or domain registry to help you with this.
