I think we all know about Tumblr, the feature rich and free blog hosting platform. It offers professional and fully customizable templates. It’ll be like ‘social network’ experience. If you want to make your Tumblr blog more professional and to give it a true identity, then using custom domain name is the best choice. Earlier we also shared how to setup custom domain name for Posterous and now we are going to do the same for Tumblr.
Tumblr Blog URL: http://blogname.tumblr.com
Custom Domain Name: http://blogname.com
If you don’t have a custom domain name, you can register one easily at GoDaddy. Confused about selecting a good domain name? Here are some tips for that.
1. Login to your GoDaddy account and go to your required domain name’s DNS Manager. Now don’t be afraid you just want to change the A record (or CNAME record) for your domain.
Click “Add Record” now.
Domain Configuration
1. Two Levels
If you want your blog URL to be domainname.com, then select Record Type as A (Host), type Host Name as @, and point to this IP address 66.6.44.4

2. Three or More Levels
If you want your blog URL to be something like blog.domainname.com or status.domainname.com, then select the Record Type as CNAME (Alias), enter Alias name as blog or status, and point to domains.tumblr.com Host Name.

Now that’s all you have to do in your domain registrar account (GoDaddy here). Now go to your Tumblr account.
2. Log into your Tumblr Account.
Go to the specific blog’s settings. There you’ll have option to use custom domain name for your blog.

Type your domain name and test it. If everything is OK, then you’ll get a success message. If the configuration is still processing, you’lll get a message like this below. You don’t need to be afraid (again), this happens after re-configuring your domain. You should wait up to 72 hours for the changes to take effect.

When you visit the subdomain or domain, you should see a Tumblr error page, that means the domain is correctly pointing to Tumblr, but that your blog hasn’t been configured to use it yet. It’ll take some time.
If you have any issues configuring this, kindly let us know in the comments below. Thanks.
