The following restrictions apply to components and features when using IPv6: 
               	 
            
 
            	 
             
               		
               - CAS support for IPv6 is limited. Some features might not work with IPv6. 
                  		
               
- IPv6 has not been tested with traditional CCI clients and servers such as Fileshare. 
                  		
               
- IPv6 address zone indexes, also known as scope IDs, are ignored by 
                  		  Enterprise Server. These appear in IPv6 addresses as a percent sign followed by a number or string, appended to the main part of the address,
                  and are used to identify a network interface when an address is not globally unique. 
                  		
               
- There are cosmetic issues with IPv6 addresses in some contexts, such as in ESMAC. 
                  		
               
 IPv6 support for 
               		Enterprise Server for .NET is unchanged since 5.0.
