#APNIC: « #Scaling the #Root of the #DNS »
« At the moment we have options as to how the service can evolve.

By #deflecting some of the current load to delegation points lower in the domain #hierarchy we can make a massive change in the current root query #load.

By having resolvers make better use of #signed #NSEC records we can stave off some of the more pressing immediate issues about further scaling of the root system.

But that’s probably not enough. »
