Our ISP provider (SANET) offers an IPTV service, where the list of TV/radio programs is offered using SAP multicast at IPv4 address of 126.96.36.199. However, my PC (with Win 10 OS installed) stopped receiving the SAP announcements, and the playlist was just empty. All works fine but once it stopped. Even better, it works for some of my colleagues, but not for others
My PC runs dual-stack, i.e. my network works with IPv4/IPv6. My PC has several network adapters as I’m running some virtualization software.
