A pure IPv4 Apex One server
Any pure IPv4 custom update source
Trend Micro ActiveUpdate server
Similarly, a pure IPv4 Update Agent cannot update directly from pure IPv6 update sources, such as a pure IPv6 Apex One server.
A dual-stack proxy server that can convert IP addresses, such as DeleGate, is required to allow the Update Agent to connect to the update sources.
