Hi there,

you don't get it

if i want to ask for your SOA or NS-records then i ask for them

there is *NO POINT* you can prohibit that unless you need a working nameserver and the only thing you *could* achieve is that i need more queries than normally needed raising the load on your own namesever

what would happen if you can achieve it:

* in the best case no difference
* in the worst case broken clients and degraded service

prohibit things just for the sake of prohibit them is clueless, dangerous and unless you have a *real good* reason for your goal you should ask yourself if you *really* have the knowledge to maintain public nameservers - sorry - impossible to say that more polite

laptop3:~$ >>> dig -t any lloyds.co.uk

tells me that there is another clueless idiot degrading services as it often happens - the larger the comapny the more foolish admins

WHAT do the gain with it?
NOTHING
