How to Set Up a Custom Domain on Ghost with 3DNS

Requirements

You must own an onchain domain from 3DNS.

Before you begin, you need to know which DNS records to copy from Ghost before adding them to your 3DNS website. Depending on whether you're using a root domain, subdomain, or non-www subdomain, the records you'll need will vary:

Root Domain DNS Configuration
Record Type	Host	Value
`CNAME`	`@`	`[subdomain].ghost.io`
`A`	`www`	`178.128.137.126`

Subdomain DNS Configuration
Record Type	Host	Value
`CNAME`	`www`	`[subdomain].ghost.io`
`A`	`@`	`178.128.137.126`

Non-www Subdomain DNS Configuration

Subdomain DNS Configuration
Record Type	Host	Value
`CNAME`	`blog`	`[subdomain].ghost.io`

Step 1. Update DNS Settings for your 3DNS Domain

Log into the 3DNS app (app.3dns.box)

Find and click on the Web tab.

Select Add DNS Record under the DNS Records tab.

Add the CNAME provided by Ghost, the CNAME differs depending on your domain type.

After making the necessary modifications to the DNS records, ensure you select "Add Record" to save the changes.

Step 2. Activate the Custom Domain

Go to Ghost(Pro) > Domain settings in the admin panel.

Click the “Setup” button.

Enter your custom domain in the designated field.

Click “Activate” to enable your custom domain.
