2409:: is replying the ICMPv6 request, in case anyone interested

This is sad, and I would either propose that Cogent/Sprint (I assume 2600:: is under the ownership of Cogent now) revive this address as it's a very helpful testing address that is burned into the minds of many. Or at the very least, I'm more than willing to tank the effort of responding to ICMP!
