NXNSAttack: Recursive DNS Inefficiencies and Vulnerabilities http://www.nxnsattack.com/dns-ns-paper.pdf

The NXNSAttack is more effectivethan the NXDomain attack:
 i) It reaches an amplifica-tion factor of more than 1620x on the number of packetsexchanged by the recursive resolver. 
 ii) Besides the neg-ative cache, the attack also saturates the ‘NS’ resolvercaches.

In an attempt to mitigate the attack impact, we propose enhancements to the recursive resolvers algo-rithm to prevent unnecessary proactive fetches.

Even with just a few domains to manage, expiration dates can be missed and this can lead to unexpected downtime.
