在同一应用程序中使用 IPv6 和 IPv4

Question

I have a SNMP Manager written in C++ using the MG Soft SDK. Till now it only sends Get and receives Trap with IPv4. Now a second SNMP Agent shall be connected but this one has IPv6. Is it possible with one application to get a connection to one remote system with IPv4 and to another one with IPv6 at the same time with the same networkcard? or do I need 2 networkcards, one for IPv4 and the other for IPv6?

Answer 1

Yes, it is possible. You just need to open 2 separate connections from within your application - one using IPv4, the other using IPv6 (of course this requires you to implement support for both IPv4 and IPv6 protocols in your application).

It works the same way as if you wanted to open multiple IPv4 connections from within the same application.

For instace, web browsers open separate connections for separate webpages you visit. They, of course, can connect to one web server using IPv4, while at the same time being connected to another web server via IPv6.
