The Melco and DS both have their own IP. The router recognizes the Melco and DS (connected via the dedicated Melco player port). Although it’s possible to assign both with a static IP address i prefer to use dynamic with the router assigning IP’s for both.
Have to correct my statement “ like the Melco -acting as DHCP server- they need to deliver the IP-address to the DS/Bridge (set to dynamic IP)”. This is only in case using the Melco in ‘direct mode’ (which allows to connect to DS to the Melco without internet/router). This is not necessary with the DS connected to internet via the Melco (or other audioserver), assigning IP addresses for both by the router.
Sorry for the confusion.
