Abstract

Generally described, the present disclosure is directed to managing request routing functionality corresponding to resource requests for one or more resources associated with a content provider. The processing of the DNS requests by the service provider can include the selective filtering of DNS queries associated with a DNS query-based attack. A service provider can assign DNS servers corresponding to a distributed set of network addresses, or portions of network addresses, such that DNS queries exceeding a threshold, such as in DNS query-based attacks, can be filtered in a manner that can mitigate performance impact on for the content provider or service provider.

Claims20

Dependent claims

A system comprising:

a DNS query processor, at a service provider, coupled to memory and operative to:
determine whether DNS queries associated with an identifiable domain exceed a threshold number of DNS queries that can be processed by a service provider;
determine whether to filter one or more DNS queries based on the threshold number of DNS queries;
cause the filtering of one or more of the DNS queries, wherein the filtering of one or more of the DNS queries comprises filtering one or more of the DNS queries based on assigned network addresses for a DNS server authoritative for the identified domain;
determine whether DNS queries associated with a different identifiable domain exceed a threshold number of DNS queries that can be processed by the service provider;
and
determine not to filter the one or more DNS queries associated with the different identifiable domain, wherein the determination corresponds to a percentage of DNS queries allowed to be processed.
