Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. We are trying to decide which DNS hosting solution to use. The best solution for us would be using Amazon's route53 for this.

Can anyone explain what this means? In particular what is supported and what isn't as well as what does using another DNS service provider for a domain that is registered with route53 mean. Those two services have no necessary connection to each other. You can register a domain with any accredited registrar for example, let's say Go Daddyand still host the DNS with Route The emphasis is intended to be on differentbecause many other service providers blur the distinction between domain registration and authoritative DNS hosting to the point that many users seem unaware nfc amiibo deity link they can almost always be decoupled, in at least one direction, regardless of the providers in question.

Question feed.It is a highly scalable web service that can be used as internal DNS hostings. With Route53 you can host multiple internal domain names within your VPC or group of VPCs which are visible and accessible to the internal hosts only and blocked for external traffic. This gives us a feasibility of calling our internal resources, ie. Application servers, Database servers, Load balancers with a friendly name according to our choice. That means if the VPC is That also means that any machine on any subnet within this VPC will be able to talk to this resolver for internal private zones as well as external internet dns queries.

Here is when forwarder comes into picture. There are many ways to configure the forwarder. Here in this blog, we will see how Unbound can be used to serve our purpose. Unbound is a recursive caching DNS server which will be used as a forwarder to forward all the queries for a specified domain to the VPC resolver.

You also need to ensure that the VPN clients are using the new forwarder as their primary nameserver. Similarly, you can utilize Unbound to forward all requests originating from AWS to the extended data center. And my VPN client is using in the resolv. AWSTechnology.

Before you start to forward queries, you must create Resolver outbound endpoints in the connected VPCs.

These endpoints provide a path for inbound or outbound queries. Check the examples folder for the simple and the complete snippets. This example creates two rules in a outbound endpoint, using all the parameter expected for building the rules:. Skip to content.

We're sorry we let you down. If you've got a moment, please tell us how we can make the documentation better. The Route 53 Resolver console includes a wizard that guides you through the following steps for getting started with Resolver:. For outbound endpoints, create one or more forwarding rules, which specify the domain names for which you want to route DNS queries to your network. If you created an outbound endpoint, choose the VPC that you want to associate the rules with.

Inbound and outbound : The wizard guides you through settings that let you both forward DNS queries from resolvers on your network to Resolver in a VPC, and forward specified queries such as example. Outbound only : The wizard guides you through settings that let you forward specified queries from a VPC to resolvers on your network.

If you chose Inbound and outbound or Inbound onlyenter the applicable values for configuring an inbound endpoint.

Then continue with step 7. For more information, see Values that you specify when you create or edit inbound endpoints. Enter the applicable values for configuring an outbound endpoint. For more information, see Values that you specify when you create or edit outbound endpoints. If you chose Inbound and outbound or Outbound onlyenter the applicable values for creating a rule. For more information, see Values that you specify when you create or edit rules.

On the Review and create page, confirm that the settings that you specified on previous pages are correct. If necessary, choose Edit for the applicable section, and update settings. When you're satisfied with the settings, choose Submit. Creating an outbound endpoint takes a minute or two. You can't create another outbound endpoint until the first one is created. If you want to create more rules, see Managing forwarding rules.

If you created an inbound endpoint, configure DNS resolvers on your network to forward the applicable DNS queries to the IP addresses for your inbound endpoint.

Learn how your comment data is processed. Resolver performs recursive lookups against public name servers for all other domain names. To use inbound or outbound forwarding, create a Resolver endpoint in the VPC. As part of the definition of an endpoint, specify the IP addresses to forward inbound DNS queries to or the IP addresses that outbound queries to originate from.

To forward selected queries, Resolver rules can be created that specify the domain names for the DNS queries that you want to forward such as example. If a query matches multiple rules example.

Thanks for letting us know this page needs work. We're sorry we let you down. If you've got a moment, please tell us how we can make the documentation better. For all other domain names, Resolver performs recursive lookups against public name servers. Your network can include any network that is reachable from your VPC, such as the following:.

These endpoints provide a path for inbound or outbound queries:. To forward selected queries, you create Resolver rules that specify the domain names for the DNS queries that you want to forward such as example. If a query matches multiple rules example. In each region where you have VPCs, you can choose whether to forward queries from your VPCs to your network outbound queriesfrom your network to your VPCs inbound queriesor both.

Resolver doesn't support VPC dedicated instances. To use inbound or outbound forwarding, you create a Resolver endpoint in your VPC. As part of the definition of an endpoint, you specify the IP addresses that you want to forward inbound DNS queries to or the IP addresses that you want outbound queries to originate from.

You configure resolvers on your network to forward DNS queries for the applicable domain names to the IP addresses that you specified in the inbound endpoint.

For more information, see Considerations when creating inbound and outbound endpoints. A web browser or another application on your network submits a DNS query for a domain name that you forwarded to Resolver. A resolver on your network forwards the query to the IP addresses in your inbound endpoint. Resolver gets the applicable value for the domain name in the DNS query, either internally or by performing a recursive lookup against public name servers.

Using the value that was returned by Resolver, the application submits an HTTP request, for example, a request for an object in an Amazon S3 bucket. Creating an inbound endpoint doesn't change the behavior of Resolver, it just provides a path from a location outside the AWS network to Resolver. A VPC security group. You create one or more rules, which specify the domain names of the DNS queries that you want Resolver to forward to resolvers on your network.

You also specify the IP addresses of the resolvers. For more information, see Using rules to control which queries are forwarded to your network. Autodefined rules — Resolver automatically creates autodefined rules and associates the rules with your VPCs. Most of these rules apply to the AWS-specific domain names that Resolver answers queries for.

For more information, see Domain names that Resolver creates autodefined system rules for. Custom rules — You create custom rules and associate the rules with VPCs. Currently, you can create only one type of custom rule, conditional forwarding rules, also known as forwarding rules.

If you create a forwarding rule for the same domain as an autodefined rule, Resolver forwards queries for that domain name to DNS resolvers on your network based on the settings in the forwarding rule. Conditional forwarding rules — You create conditional forwarding rules also known as forwarding rules when you want to forward DNS queries for specified domain names to DNS resolvers on your network.

System rules — System rules cause Resolver to selectively override the behavior that is defined in a forwarding rule. When you create a system rule, Resolver resolves DNS queries for specified subdomains that would otherwise be resolved by DNS resolvers on your network.

By default, forwarding rules apply to a domain name and all its subdomains. If you want to forward queries for a domain to a resolver on your network but you don't want to forward queries for some subdomains, you create a system rule for the subdomains.

For example, if you create a forwarding rule for example. Recursive rule — Resolver automatically creates a recursive rule named Internet Resolver. This rule causes Route 53 Resolver to act as a recursive resolver for any domain names that you didn't create custom rules for and that Resolver didn't create autodefined rules for.

For information about how to override this behavior, see "Forwarding All Queries to Your Network" later in this topic. You can create custom rules that apply to specific domain names yours or most AWS domain namesto public AWS domains names, or to all domain names.In a previous postI showed you a solution to implement central DNS in a multi-account environment that simplified DNS management by reducing the number of servers and forwarders you needed when implementing cross-account and AWS-to-on-premises domain resolution.

With the release of the Amazon Route 53 Resolver service, you now have access to a native conditional forwarder that will simplify hybrid DNS resolution even more. This solution allows you to resolve domains across multiple accounts and between workloads running on AWS and on-premises without the need to run a domain controller in AWS.

Figure 2: Use case for resolving on-premises domains from workloads running in AWS. If the server with private domain host1. In this flow, the DNS query that was initiated in one of the participating accounts has been forwarded to the centralized DNS server which, in turn, forwarded this to the on-premises DNS.

Figure 3: Use case for how on-premises workloads will be able to resolve private domains in your AWS environment.

In this case, the query for host1. Finally, you might need to resolve domains across multiple AWS accounts. Figure 4: Use case for how to resolve domains across multiple AWS accounts.

aws route53 resolver

For each participating account, you need to configure your VPCs to use the shared forwarding rules, and you need to create a private hosted zone for each account. At this point, you should be able to resolve on-premises domains from workloads running in any VPC associated with the shared forwarding rules.

In this step, you need to create a private hosted zone in each account with a subdomain of awscloud. Use unique names for each private hosted zone to avoid domain conflicts in your environment for example, acc1. To do that, you need to create authorization from the account that owns the private hosted zone and accept this authorization from the account that owns DNS-VPC. To be able to resolve subdomains within the awscloud.

Thanks to the flexibility of Route 53 Resolver and conditional forwarding rules, you can control which queries to send to central DNS and which ones to resolve locally in the same account. In this section, I will name two use-cases that require additional considerations. This option associates a private hosted zone with your VPC. The hosted zone contains a record set for the default DNS name for the service for example, ec2.
