About domain label settings
Domain label settings are under Networking > App Definitions: Domain Labels.
Name specifies the label name.
Domains specifies a comma-separated list of domains. Keep in mind that some services might use alternate domains. For example, www.box.com might also use srv1.box.net. IP addresses are not supported. These rules apply to domain label entries:
• Matching is not case sensitive.
• You must include a top and second-level domain: for example, *outlook.com. You cannot include a wildcard in a top-level domain.
• You can also separate domains with spaces or new lines.
• A domain name segment (also known as a label) can be up to 64 characters long.
• Characters must be alphanumeric (0-9, a-z, A-Z), periods, underscores, wildcards, or hyphens.
• Do not use consecutive periods or wildcards.
