The following table lists the limitations when the Security Agent only has an IPv6 address.
| 
 Item  | 
 Limitation  | 
|---|---|
| 
 Parent Apex One server  | 
 Pure IPv6 Security Agents cannot be managed by a pure IPv4 Apex One server.  | 
| 
 Updates  | 
 A pure IPv6 Security Agent cannot update from pure IPv4 update sources, such as: 
  | 
| 
 Scan queries, web reputation queries, and Smart Feedback  | 
 A pure IPv6 Security Agent cannot send queries to smart protection sources, such as: 
  | 
| 
 Software safety  | 
 Pure IPv6 Security Agents cannot connect to the Trend Micro-hosted Certified Safe Software Service.  | 
Plug-in solutions  | 
Pure IPv6 Security Agents cannot install plug-in solutions because none of the plug-in solutions support IPv6.  | 
| 
 Proxy connection  | 
 A pure IPv6 Security Agent cannot connect through a pure IPv4 proxy server.  | 
Most of these limitations can be overcome by setting up a dual-stack proxy server that can convert between IPv4 and IPv6 addresses (such as DeleGate). Position the proxy server between the Security Agents and the entities to which they connect.
