Ok- I dont want to start a flame war on this topic, so please keep comments related to the problem, not "re-implement the system with something else". I have 2 cacheing DNS servers that are hit hard- (as in billions of requests per day, at least) In order to keep this running smoothly, we use djbdns as its the fastest we can find for our particular application, and we are not willing to change that at the moment. However, a few domains that occationally get requested have bad information, and we would like to "blacklist" them by providing ourselves as the authorty for them (to just the cacheing DNS servers), and point them back to our own servers. The probem is you cannot run a cacheing server on the same IP as a full DNS server. Keeping in mind performance is a key issue here, does anyone have any suggestions to implement this?
