Syntax for DNS Host Names

There are many places where you can enter a FQDN or an IP address. If your DNS host names include an underscore or in any way do not conform to the required syntax, specify the IP address.

Valid DNS host names:

• Begin with an alpha character.
• End with an alphanumeric character.
• Contain 2-24 alphanumeric characters.
• Can contain the special character (-) minus sign.

  Important! The minus sign (-) is the only valid special character permitted in DNS host names.
