ECP: SSDP gives me wrong IP after a while
I am playing with ECP and my Roku. When I use SSDP to discover my box, it gives me back the correct IP, but after a while the IP seems to have changed for the box and the SSDP call still gives me back...

Opening hundreds of hanging TCP connections is a horrible idea, please do not suggest it!
I think the idea is to ping all the IPs to see what replies - and then open the TCP connection between those addresses that are in use - in most home LANs you're talking about fewer than 10 devices. The roku always replies to ICMP.

But i hear you on the icmp ping idea. That will work - that is unless some router has automated protection from network scans (i.e. mass icmp trips blockage)
