the IP-adress of this PC is well known, we do nothing with IP6. ping with -4 param shows the correct IP-Adress, ping without params brings IP6
when we “call” the localhost Server the first time via Xibo Player Options we have no posibility to modify wether IP4 or IP6 is transmitted
may be this is because Server and Client are on the same machine. we have another Installation with both Server and Client on the same PC and IP-Adress Shows ::1 also.
