XS4ALL IPTV multicast sources changed

Some of my XS4ALL (KPN) IPTV channels stopped workking properly. The started to stutter, normally an indication of trouble at multicast subscriptions. Looking at the logfile (while the little one was trying to watch BabyTV) I found the culprit:

The source address 217.166.226.39 for group 224.0.252.39, is not in any valid net for upstream VIF[0]. This address is part of a multicast block 217.166.0.0/16 assigned to KPN.

Adding this new network to file:/usr/local/etc/igmpproxy.conf using the altnet 217.166.0.0/16 made it all work again.
