Disable Recursive DNS/DNS Recursion

Recursive DNS queries happen from time to time. This occurs when a DNS server that does not “own” a domain is asked to query more DNS servers until DNS information and an answer are returned.

Fake requests that flood the server with the results of each inquiry can make servers with recursive DNS searches susceptible. This causes the server to become overburdened with traffic that it cannot handle. The performance eventually deteriorates. It’s referred to as a DOS/DDOS (Denial of Service/Distributed Denial of Service) attack in this situation.

DNS Recursion can be disabled on your server in a number of ways. Simply follow the instructions outlined below:
