Thanks, you are right, although the DVB specifications don't actually 
say that IRDs should stop functioning in case of reserved values being 
used. In fact, most of the specs say that reserved values should just be 
ignored. I guess you can interpret that in many ways, but IMO the most 
robust interpretation is just to not make any assumptions of the ID if 
it's from an unknown range, and simply use it as it is.

(The network I'm on has been using original_network_id 0 for some reason 
for ~5 years but so far every DVB-C STB has managed to tune properly...)
