Edit a subdomain

A subdomain is a type of DNS record that adds a prefix to your domain, such as blog.mycoolnewbusiness.com. You can edit an existing subdomain that uses an IP address in your DNS zone file at any time. 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 Screenshot showing the three-dot icon to select domain edit options Domain Edit Options next to your domain and then select Edit DNS. You may need to scroll down to see Edit DNS.

    • To edit a single DNS record, select screenshot of the icon for editing a dns record Edit next to the specific record you'll be editing.
    Note: If you can't edit a DNS record, make sure you don't have forwarding on the domain, and that your Website Security IP address is correct.
  4. Enter the details for your A record subdomain:
    • Name: The hostname or prefix of the record, without the domain name such as blog or shop.
    • Value: The IP address the A 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. Select Save to confirm your edits. If you added multiple records at the same time, select Save All Records.

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