If a discovery candidate system is presented as a hostname without an explicit IP version suffix (:v6v4, :v4v6, :v6, or :v4), the SM_IP_VERSIONS environment variable controls how the local name resolution service resolves the hostname to a corresponding IP address. By default, SM_IP_VERSIONS is set to v6v4. For v6v4, the name resolution service resolves a hostname to an IPv6 address, or if that resolution fails, to an IPv4 address.

The hostname syntax and the SM_IP_VERSIONS environment variable are described in the VMware Smart Assurance IP Manager Reference Guide.
