Add a subdomain

A subdomain is a type of DNS record that adds a prefix to your domain, such as blog.mycoolnewbusiness.com. You can create a subdomain that uses an IP address by adding an A record to your DNS zone file.  If you need a subdomain that connects to another domain name, you'll need to add a CNAME record instead.

1. Sign in to your GoDaddy Domain Portfolio. (Need help logging in? Find your username or password.)
2. Select an individual domain to access the Domain Settings page.
   
3. Select DNS to view your DNS records.
   
4. Select Add New Record and then select A from the Type menu.
5. Enter the details for your new A record subdomain.
   
   
• Name: The hostname or prefix of the record, without the domain name such as blog or shop. The Name must follow these guidelines:
  
  
• Periods (.) are allowed but not as the first or last character
• Consecutive periods (…) are not allowed
• Cannot begin or end with a hyphen (-)
• 63 characters in a row not separated by a period (.)
  
  

• 255 characters maximum
• Value: The IP address the record will point to. This is commonly the IP address for a hosting account.
  
  
• Select Add another value to add more IP addresses to this A record.
• TTL (Time to Live): The amount of time the server should cache information before refreshing. The default setting is 1 hour.
5. (Optional) Select Add More Records to add multiple DNS records at the same time. If you change your mind, select  Delete to remove any records that haven't been saved yet.
6. Select Save to add your new record. If you added multiple records at the same time, select Save All Records.
   
   
• If your domain has Domain Protection, you'll need to verify your identity. If you've had 2 step-verification (2SV) turned on for at least 24 hours, enter the code we sent via SMS, or enter the code from your authenticator app. Otherwise, enter the one-time password we sent to your registrant email address.

Most DNS changes take effect within an hour but could take up to 48 hours to update globally.
