Air Staff merely confirmed what I already told you - it's out of Airs' hands. You'll note they mention residential IPs too.
So it inherently doesn't matter if you change to something other than Air, as those IPs would also just get blocked.
So nowadays it's hit and miss.
Such is the problem when sites block users. Other big ones like Netflix are notorious for it too. Best of luck.
Sorry, I don't buy this.
BBC will be blocking IP's either from publicly available IP lists of VPN services, or on a case-by-case basis, where they detect 20+ streams from one single IP & suspect it is a VPN.
AirVPN has a routing server in the UK, GB2, which is hardly used - https://airvpn.org/servers/GB2/
I don't understand why they can't route all Iplayer traffic via that server, & when it gets blacklisted by BBC, just contact the data centre & get it issued with another IP. This won't affect any end user connection/configuration as the IP addresses of the servers we connect to will remain unchanged.
Iplayer downtime would then be limited to how quickly AirVPN can provision another routing server that isn't blacklisted.
Clearly many users find this to be a big deal - I don't understand why this is not worth doing!
