Overview
The following is a brief overview of Wildcard DNS and how it is implemented at DreamHost.
Background
Wildcard DNS is used to provide DNS records for subdomains that do not exist. For example, if your website is example.com, you can manually create a subdomain named blog.example.com. However, sometimes it may be necessary to use a subdomain that you have not created. In this case, Wildcard DNS can provide this DNS record using the * symbol. For example:
- *.example.com
FAQs
Is Wildcard DNS available at DreamHost?
-
Wildcard DNS can be enabled only on a VPS or Dedicated Server. This is due to the high resource usage (and potential abuse) that usually comes with installing software that relies on Wildcard DNS in order to function.
How can Wildcard DNS be enabled?
-
Wildcard DNS can be enabled by submitting a support request. Before creating this request, make sure:
- This is a service you absolutely need
- The domain is currently running on a VPS or Dedicated Server
- You're aware of the technical implications of setting up a Wildcard DNS entry on your domain
Can I install Wildcard DNS myself?
-
There is no access to install this type of software on managed DreamHost servers, including VPS and Dedicated Servers.
However, you have the option of creating a cloud server using DreamCompute, DreamHost's cloud computing service. This is a fully unmanaged service where you have full control over the server, allowing you to install any software you like.
Please note that technical support is unable to assist with customizations made to a cloud server. If you choose to use this option, you must be ready to install and troubleshoot all software issues that may arise.
Is Wildcard DNS the same as a Wildcard SSL certificate?
-
No. These are separate services. It's currently not possible to use a Wildcard SSL certificate at DreamHost. See this article for further details.
