SLAAC (Stateless Address Autoconfiguration):

IPv6 commonly uses SLAAC for automatic address assignment. Your router will broadcast information about the network, including the network prefix, and your host will generate a unique interface ID (often derived from its MAC address) to create a full IPv6 address. 

 

Ensure IPv6 is properly configured across your router, host, docker, and (if used) virtual machines. Misconfigured IPv6 settings can lead to connectivity issues.

mdns forwarding

Enable mDNS forwarding to allow communication between devices on different network segments.

IGMP Snooping

If not configured properly, IGMP Snooping may cause the suppression of mDNS messages. For this reason, it is recommended to disable it on networking devices such as switches and, if applicable, Hypervisors & Access Points

 

Firewall

Ports: Verify that required ports (e.g., 5353, 5540, 5541 - TCP & UDP) are open and correctly routed.
