I did not write any code concerning connections.

I was just using the web server example, which I checked from the browser on my development machine.

The NIOS web server responded on one IP address, the IP address was changed, and the NIOS responded on the new IP address.

But HTTP is not a protocoll where connections are kept open for long.

So I have not changed the IP during an active connection.

But, I'd assume the TPC stack drops all packets that don't match the IP address (as it probably should).

The server however starts responding as soon as the new IP address is in place.
