You can use VPN or not, both are OK.
With the rise of IPTV streaming taking over the older ways of satellite boxed and cable boxes VPNs have been running alongside offering great benefits to IPTV users that cover extra performance and privacy as opposed to not using a VPN.
One of the main issues we currently see in the IPTV market is internet providers being forced to live block IPTV servers when there is a football game on. This has a big impact if your IPTV providers get blocked as the block can last for over 4 hours and you miss the game you have been waiting to watch.
Luckily AirTV IPTV does not have this issue so you don’t need to use a VPN at all but sometimes it may be more beneficial to use one to make sure you are getting the best performance without any ISP bandwidth throttling they can sometimes do.
