IPv6 communication

[<thekkayil.joy at wipro.com>]

Hi,

     We are analyzing for migrating to IPv6. As part of this activity, we are successful

 

in scenario A but failing in Scenario B:

 

Scenario A. Communication between IPv6 client application on dual layer node and  IPv6 server application on dual layer node[Vista].

 

Scenario B. Communication between IPv6 Client application on dual layer and IPv4 server application on IPv4 only node.

 

We are getting a failed getaddrinfo() in Client application before even calling the sendto(). In getaddrinfo, we are trying to get the IPv4 compatible IPv6 address(by specifying AF_INET) for the host name of the server.

 

Is there a need to use Naming service say DNS?

 

Regards,

T J Thomas
