resolve ip addresses

Domain-name system (DNS) suffixes have the following two primary purposes:

1. When appended to the server appliance host name, DNS suffixes constitute
the fully qualified server appliance name.

2. DNS suffixes are used to resolve IP addresses. If your server appliance
is a member of Windows NT 4 domain, a Microsoft Active Directory, or a workgroup,
the DNS suffix is dependent upon the domain environment. Including hyphens and periods,
a DNS suffix may contain up to 155 characters.
