Original Pull Request: https://github.com/jellyfin/jellyfin/pull/11766

State: closed
Merged: Yes

Currently, we are assuming all IPs not in user-set subnet are external IPs, but this is not accurate enough:

  • IPv4 addresses are not in IPv6 subnets and vice versa, and we will be returning IPv4 binding address as IPv6 external IP

  • Link Local Addresses are not considered as LAN address in most cases, but we are treating them as external address if available and that is wrong because such addresses are not route-able.
