A site owner or core team member can configure a site with a custom domain that they own or one purchased to uniquely represent the site. The site will remain accessible over its default *.arcgis.com URL, alongside the custom domain.
Create a CNAME record
ArcGIS Hub only supports CNAME domain name service (DNS) entries. Custom domains must be registered as a CNAME record that points to hub.arcgis.com. To get started, sign in to your DNS provider and create a CNAME entry. What each field is called will depend on your DNS provider. Typically, Name or Hostname is the prefix or sub-domain (appears before the domain in the URL) to which the CNAME record will be set: yourhubsitename. Value or Data is usually the URL you are setting as the destination domain: hub.arcgis.com. It may take up to 24 hours for a security certificate to be issued to your custom domain. If it has been longer than 24 hours, please contact Esri Support.
Do not register your CNAME to your specific Hub site. You must register the CNAME to hub.arcgis.com exactly. This allows you to move the domain between your sites.
Add the custom domain to your site
Once you’ve created with a CNAME record, you can configure your site’s web address with the new domain.
- Open a site in edit mode.
- In Settings on the side panel, click Domain Settings.
- Click Modify Domain Settings and choose Custom Domain.
Ensure that you've created a CNAME record and proceed to the second step to validate the CNAME.
Once the CNAME has been validated, you must confirm that you understand that updating your site's URL with its new domain may take up to 24 hours to complete.
- Click Done.An email is sent from arcgis.com to the site's owner and core team members to remind them that the site's URL is being updated. During this time, you can continue to publish updates to the site at its current URL. An additional confirmation email is sent once the domain has been successfully updated.
To check the status of the domain update, click the Save drop-down menu and choose Preview site.
Set up a site redirect
If you edit or change your site's primary (custom or default) domain, you can set a redirect URL. This domain redirect must follow the custom domain format (above).
