Abstract
In a network, Domain Name Service (DNS) queries may be handled by one or more resolvers and one or more authoritative name servers. If a DNS distributed denial of service attack is launched against the network, it may degrade the performance of the authoritative name servers. As such, systems and methods for protection of authoritative name servers are provided.
