YouView Player, iPlayer, 4oD etc Netblocks

[Qtx]

Does anyone know if there is a list of IP addresses or Netblocks anywhere for catchup and on demand services?

I want to create static routes on my firewall for these services so the tv can access them directly instead of going out through a VPN in another country with the rest of my traffic, while at the same time staying on the same subnet behind the firewall so it can stream files from Plex/DLNA servers.

The tv has Youview player which i don't think has geo-restrictions itself but its only a front end for the actual iPlayer/4oD etc players.

Any link, lists or advice appreciated.
