Abstract: Systems and methods are provided for domain name system (DNS) resolutions in a network environment that includes multiple virtual private clouds (VPCs) attached indirectly to each other via a transit gateway that serves as a hub in a hub and spoke model. An administrator of a VPC may specify rules for resolving DNS resolution requests at the given VPC, and the rules may be taken into account by DNS resolvers at other VPCs attached to the same transit gateway based on information propagated by the transit gateway.
