The IPv6 requirements for the OfficeScan server are as follows:
The server must be installed on Windows Server 2008, Windows Server 2012, or Windows Server 2016.
The server must use an IIS web server.
If the server will manage IPv4 and IPv6 OfficeScan agents, it must have both IPv4 and IPv6 addresses and must be identified by its host name. If a server is identified by its IPv4 address, IPv6 OfficeScan agents cannot connect to the server. The same issue occurs if pure IPv4 agents connect to a server identified by its IPv6 address.
If the server will manage only IPv6 agents, the minimum requirement is an IPv6 address. The server can be identified by its host name or IPv6 address. When the server is identified by its host name, it is preferable to use its Fully Qualified Domain Name (FQDN). This is because in a pure IPv6 environment, a WINS server cannot translate a host name to its corresponding IPv6 address.
The FQDN can only be specified when performing a local installation of the server. It is not supported on remote installations.
