Tumblr is a micro-blogging service that offers you the ability to replace your Tumblr URL with an external domain. It requires you to change the DNS A record for your registered domain to Tumblr's IP address.

This article describes how to configure a custom domain registered with DreamHost for use with Tumblr as well as setting up optional DNS records for Round Robin DNS protection. View Tumblr's help page for further information. You will need to create one of the following DNS records.

  • If your domain has two levels (example.com), point the A record to
  • If your domain has three or more levels (www.example.com or blog.example.com), point a CNAME record to domains.tumblr.com

Setting your domain to DNS Only

Before adding a custom DNS record, you must set your domain to DNS Only. This removes DreamHost's DNS records from your domain. View the following article for instructions.

Adding DNS records

The type of record you create depends on how many levels your domain uses. View the sections below to determine which type of record to add.

Creating an A record

If your custom domain contains two levels (e.g., example.com), you must create an A record. View the following article for instructions on how to add this record type:

Enter the following:

  • Host: Leave this field blank
  • Points to:
A record

Creating a CNAME record

If your custom domain contains three or more levels (e.g., www.example.com or blog.example.com), you must create a CNAME record. View the following article for instructions on how to add this record type:

Enter the following:

  • Host: Your subdomain (for example: www)
  • Points to: domains.tumblr.com
CNAME record

Finishing the setup

  1. Log into your Tumblr account.
  2. Click the Settings button under the account menu at the top of the dashboard.
  3. Select the blog you'd like to update.
  4. Click the pencil to the right of the Username section (the Tumblr URL section for secondary blogs), and then enable Use a custom domain.
  5. Enter your domain (e.g., example.com) or subdomain (e.g., blog.example.com). Then click Test your domain.
