-In order for Chromecast to work on a non-public routable connection, 8.8.8.8 must be blocked on the Chromecast's Gateway. Blocking 8.8.8.8 on your router is the easiest solution to this problem.
+In order for Chromecast to work on your local LAN, the easiest solution is to use IPv6 instead of IPv4.
+For IPv4, you need to use NAT reflection to redirect to your local LAN IPv4 or add a override rules to your local DNS server to point to your local LAN IPv4 (for example 192.168.1.10) of Jellyfin.  
+Because Chromecasts have hardcoded Google DNS servers, you need to block Chromecast from reaching these servers (8.8.8.8) so it makes use of your local DNS server instead.  
+For a public routable IPv6 (not a link-local or ULA) there is no difference between public or local. Such IPv6 address is simultaneously publicly routable and accessible from the local LAN.  
+Because of that, there is no blocking, redirecting or DNS override needed.
