CreateReusableDelegationSet

Creates a delegation set (a group of four name servers) that can be reused by multiple hosted zones that were created by the same AWS account.

You can also create a reusable delegation set that uses the four name servers that are associated with an existing hosted zone. Specify the hosted zone ID in the CreateReusableDelegationSet request.

Note

You can't associate a reusable delegation set with a private hosted zone.

For information about using a reusable delegation set to configure white label name servers, see Configuring White Label Name Servers.

The process for migrating existing hosted zones to use a reusable delegation set is comparable to the process for configuring white label name servers. You need to perform the following steps:

Create a reusable delegation set.
Recreate hosted zones, and reduce the TTL to 60 seconds or less.
Recreate resource record sets in the new hosted zones.
Change the registrar's name servers to use the name servers for the new hosted zones.
Monitor traffic for the website or application.
Change TTLs back to their original values.

If you want to migrate existing hosted zones to use a reusable delegation set, the existing hosted zones can't use any of the name servers that are assigned to the reusable delegation set. If one or more hosted zones do use one or more name servers that are assigned to the reusable delegation set, you can do one of the following:

For small numbers of hosted zones—up to a few hundred—it's relatively easy to create reusable delegation sets until you get one that has four name servers that don't overlap with any of the name servers in your hosted zones.
For larger numbers of hosted zones, the easiest solution is to use more than one reusable delegation set.
For larger numbers of hosted zones, you can also migrate hosted zones that have overlapping name servers to hosted zones that don't have overlapping name servers, then migrate the hosted zones again to use the reusable delegation set.

URI Request Parameters

The request does not use any URI parameters.

Request Body

The request accepts the following data in XML format.

CreateReusableDelegationSetRequest

Root level tag for the CreateReusableDelegationSetRequest parameters.

Required: Yes

CallerReference

A unique string that identifies the request, and that allows you to retry failed CreateReusableDelegationSet requests without the risk of executing the operation twice. You must use a unique CallerReference string every time you submit a CreateReusableDelegationSet request. CallerReference can be any unique string, for example a date/time stamp.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Required: Yes

HostedZoneId

If you want to mark the delegation set for an existing hosted zone as reusable, the ID for that hosted zone.

Type: String

Length Constraints: Maximum length of 32.

Required: No

Response Elements

If the action is successful, the service sends back an HTTP 201 response.

The response returns the following HTTP headers.

Location

The unique URL representing the new reusable delegation set.

Length Constraints: Maximum length of 1024.

The following data is returned in XML format by the service.

CreateReusableDelegationSetResponse

Root level tag for the CreateReusableDelegationSetResponse parameters.

Required: Yes

DelegationSet

A complex type that contains name server information.

Type: DelegationSet object

Errors

For information about the errors that are common to all actions, see Common Errors.

DelegationSetAlreadyCreated

A delegation set with the same owner and caller reference combination has already been created.

HTTP Status Code: 400

DelegationSetAlreadyReusable

The specified delegation set has already been marked as reusable.

HTTP Status Code: 400

DelegationSetNotAvailable

You can create a hosted zone that has the same name as an existing hosted zone (example.com is common), but there is a limit to the number of hosted zones that have the same name. If you get this error, Amazon Route 53 has reached that limit. If you own the domain name and Route 53 generates this error, contact Customer Support.

HTTP Status Code: 400

HostedZoneNotFound

The specified HostedZone can't be found.

HTTP Status Code: 400

InvalidArgument

Parameter name is not valid.

HTTP Status Code: 400

InvalidInput

The input is not valid.

HTTP Status Code: 400

LimitsExceeded

This operation can't be completed because the current account has reached the limit on the resource you are trying to create. To request a higher limit, create a case with the AWS Support Center.

HTTP Status Code: 400
