All sites created with ArcGIS Hub are published with a web address that consists of the organization short name, site name, and a default subdomain provided by Hub. You can update your site's name in the default URL or add a custom domain that you own or one purchased by your organization.
A domain name is part of your site's web address and is a human-friendly way to identify your site's Internet Protocol (IP) address. An IP address is a series of unique characters that identifies each computer (personal device or server).
This allows a global network of computers to ask each other for information, such as directions to your site. When someone opens your site in a web browser, your device uses a domain name system (DNS) to locate your site's IP address.
Tip:
Think of a domain as the name of a contact and the IP address as the contact’s phone number or home address. Similar to a contact list, the internet uses a DNS to look up the site’s IP address.
Default domains for sites
All sites created with Hub are hosted on the default domain on arcgis.com. Site managers are required to select the hub.arcgis.com (default) or the opendata.arcgis.com subdomain. The subdomain is then combined with your ArcGIS Online organization short name and, initially, your site name to produce your site URL.
For example, if your organization's short name is mycompany and you use the default subdomain of hub.arcgis.com with your site named data, then your site's URL would be https://data-mycompany.hub.arcgis.com.
Once created, your site URL is no longer connected to your site item name, allowing you to change the site name while keeping the domain the same and vice versa.
Caution:
Changing the organization's short name after you have created sites or other ArcGIS applications is not recommended. Learn more about changing the short name. Unlike other ArcGIS applications, you cannot update a site item's application URL to resolve issues after an organization short name change. Instead, you must contact Esri Support Services to update the site's registered domain.
Update a site's default URL
A site's URL is the web address people use to access your site. You can update your site name in its URL (subdomain) or switch the base domain from the default hub.arcgis.com to opendata.arcgis.com.
To update a site's default URL, complete the following steps:
- Open a site in edit mode.
- Select the Manage site button to go to the site workspace.
- Select Settings and select the General pane to configure the site URL with the following options:
- Update the site's URL by modifying the text in the Subdomain field.
- Change hub.arcgis.com (default) to opendata.arcgis.com by using the Base domain dropdown menu.
Note:
Some organizations prefer to use opendata.arcgis.com if they have other open data sites using that base domain.
- Select Save.
Note:
To apply a custom domain to your site, you must update your domain name service record and add the full domain in ArcGIS Hub. For complete steps, refer to Use a custom domain.Proxy traffic and certificates
You cannot run traffic through a proxy server. Custom domain configurations will fail validation when the domain is added to your Hub site. You cannot use your own HTTPS certificate. For security reasons, Hub requests short-lived HTTPS certificates for sites on the platform on your behalf. Hub uses the Let's Encrypt Certificate Authority.
