Cloud No Auth Free & Open cloud

When you create a VPC using Amazon VPC, you automatically get DNS resolution within the VPC from Route 53 Resolver. By default, Resolver answers DNS queries for VPC domain names such as domain names for EC2 instances or Elastic Load Balancing load balancers. Resolver performs recursive lookups against public name servers for all other domain names. You can also configure DNS resolution between your VPC and your network over a Direct Connect or VPN connection: Forward DNS que

Sample Requests

POST ListFirewallConfigs

Retrieves the firewall configurations that you have defined. DNS Firewall uses the configurations to manage firewall behavior for your VPCs. A single call might return only a partial list of the configurations. For information, see MaxResults .
