For a seed entry that begins with a hostname, you can specify the hostname with or without an explicit IP version suffix (:v6v4, :v4v6, :v6, or :v4). Here is an example hostname that includes a v4 suffix: Core-ROUTER-1:v4.

If you do not include an explicit IP version suffix, 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 a seed entry that begins with an IP address, you can specify an IPv6 or IPv4 address. If you specify an IPv6 address and a port number, you must enclose the address in square brackets; for example: [2001:0db8::0010]:200.

Be careful not to use an overlapping IP address as a seed system.

Hostname syntax, the SM_IP_VERSIONS environment variable, and overlapping IP addresses are discussed in the VMware Smart Assurance IP Manager User Guide.
