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.
- Sign in to your GoDaddy Domain Portfolio. (Need help logging in? Find your username or password.)
- Select an individual domain to access the Domain Settings page.
- Select DNS to view your DNS records.
- Select Add New Record and then select A from the Type menu.
- 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 (.)
Example: 63characters.63characters.coolexample.com
- 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.
- Name: The hostname or prefix of the record, without the domain name such as blog or shop. The Name must follow these guidelines:
- (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. - 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.
