About domain label settings
Add a New Domain Label displays the controls to add a new domain label.
Name specifies the label name. These rules apply:
• A domain label name can be up to 64 characters long.
• Domain label names are case sensitive and can be any string consisting of letters, numbers, the underscore ( _ ), or the hyphen ( - ). There can’t be spaces in domain label names.
• We suggest starting the name with a letter or underscore, although the first character can be a number.
• To avoid confusion, don’t use a number for a domain label.
Domains specifies a comma-separated list of domains. Keep in mind that the URL might use other domains. For example, www.box.com might also use srv1.box.net and other domains. Determine all of the domains whose traffic you want to optimize, and make an entry in the domain label for each one. Domain labels are most useful when they specify a narrow destination IP range, so use the smallest destination IP/range you can. Using a host label can help to narrow the destination IP range.
These rules apply to domain label entries:
• Matching is not case sensitive.
• You must include a top-level domain: for example, .com. You cannot include a wildcard in a top-level domain.
• You must specify second-level domains: for example, *.outlook.com, but not *.com.
• You can also separate domains with spaces or new lines.
• A domain name can be up to 64 characters long.
• Characters must be alphanumeric (0-9, a-z, A-Z), periods, underscores, wildcards, and hyphens.
• Do not use consecutive periods.
• Do not use consecutive wildcards.
• Do not use IP addresses.
A domain can appear in multiple domain labels. You can create up to 63 unique domain labels.
To remove a domain label, select the check box next to the name and click Remove Selected. You can’t delete domain labels that an in-path rule is using.
Add New Domain Label adds the domain label. The page updates the domain label table with the new domain label.
