Edit a subdomain

Edit a subdomain record in your DNS zone file. Subdomains use a domain prefix, such as, as an A record to point to an IP address. To edit a subdomain that points to a domain name, you'll need to edit a CNAME.

  1. Sign in to your GoDaddy Domain Portfolio. (Need help logging in? Find your username or password.)
  2. Select alt name for the image Domain Edit Options next to your domain and then select Edit DNS. You may need to scroll down to see the Edit DNS option.

    Note: Can't edit the record? Check these settings or products:
    • Do you own Search Engine Visibility? Our GoDaddy Guides to help edit the record.
    • Is forwarding enabled on the domain? Delete forwarding to enable editing the record.
    • Is the domain connected to a 3rd-party site (e.g., Squarespace or LinkedIn)? Visit that site to disconnect it, or remove the connection to enable editing the record.
    • Is a firewall turned on in Website Security? Edit your IP address to the correct IP for your hosting account.

  4. Edit the details for your A record subdomain:
    • Name: The host name or prefix for the subdomain. For example, enter blog to create the subdomain for
    • Value: The IP address for your subdomain. This will usually be the IP address of your hosting account.
    • TTL: How long the server should cache information. The default setting is 1 hour.
  5. Select Save to complete your changes.

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