Worth Reading: Open IPv6 Resolvers Open DNS resolvers that answer queries coming from anyone have been the main component of a large number of DDoS attacks in recent years. By sending queries with a spoofed source address to such open resolvers, the resolver will send the answers to that spoofed address. An attacker spoofs the address of his/her target and sends a large number of queries to an open resolver, creating a deluge of large DNS answers towards the target. —APNIC Related
