The DNS service is a regionalized service. DNS is therefore responsible for appropriate replication, caching, and overall maintenance of DNS data across regional boundaries to other DNS servers.
The information for service endpoints is summarized in the table below.
| Region | Endpoint | |||
| US | https://dns.api.rackspacecloud.com/v1.0/1234/
|
|||
| UK |
https://lon.dns.api.rackspacecloud.com/v1.0/1234/
|

![]() | Note |
|---|---|
All examples in this guide assume that you are operating against the US region, however if you are using a different region, be sure to use the associated endpoint from the table above instead. |
Replace the sample account ID number,
1234, with your actual account
number returned as part of the authentication response.
Use your actual account number wherever you see the field
your_acct_id
specified in this guide. Refer to Chapter 5, Generate an Authentication Token.
When making a Cloud DNS API call, place the endpoint at
the beginning of the request URL, for example:
https://dns.api.rackspacecloud.com/v1.0/your_acct_id/, as
you can see in the cURL Create Domain Request examples in
Chapter 7, Create a Domain. Note that the
v1.0 component in the URL indicates that
you are using version 1.0 of the Cloud DNS API.
