Manage DNS Resolvers and Rules

You can create DNS Resolvers and DNS Rules to enhance the DNS resolution capabilities of your Stax Networking Hub. You can create one DNS Resolver per Networking Hub, but many DNS Rules to customize how DNS resolution works.

In order to use DNS Resolvers, you should already have an AWS Direct Connect or Site-to-Site VPN in place between your Stax Networking Hub and your on-premises infrastructure.
