REQUEST ROUTING PROCESSING

摘要

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.

1. A computer-implemented method for managing DNS queries comprising:
determining, at a service provider, whether DNS queries associated with an identifiable domain exceed a threshold number of DNS queries that can be processed by a service provider; determining, at the service provider, whether to filter the one or more DNS queries based on the threshold number of DNS queries; and causing, at the service provider, the filtering of at least one of the one or more DNS queries, wherein the filtering of the at least one or more DNS queries corresponds to the filtering of DNS queries based on assigned network addresses for the DNS server authoritative for the identified domain.
