When a recursive resolver receives a query for an IP address it already has in its cache, it can rapidly provide the cached answer to the client without communicating with any other DNS servers. Quickly serving responses from the cache is very likely if a) the DNS server serves a lot of ...

Servers supporting recursive DNS queries are vulnerable to phony requests that flood a particular IP address with the results of each server's query. This can overwhelm the IP address with a volume of traffic too large to be processed. DNS cache poisoning Cache poisoning results from someone tric...
