Bulk DNS

I’m usign arround 5000 different A records at favshare.com.

Now I want the wildcard '’ pointing to a new IP but to remail the actual records an te same ip 212.36.72.**.

There are some bukl DNS toolt to do that?? I trient to do it using http://wiki.dreamhost.com/Dynamic_DNS and a NQL robot but notting works (i suppose is because a security reson), but I have to point all the record.

¿What can I od?
