2012/04/06: 2012/04/06:
Implementing IPv6 support :
Send SSDP NOTIFY ssdp:alive and ssdp:goodbye messages in IPv6.
Use UPnP/1.1 in SERVER: string as required in UPnP Device architecture 1.1. Use UPnP/1.1 in SERVER: string as required in UPnP Device architecture 1.1.
Allow LAN interface to be given as interface names, instead of interface Allow LAN interface to be given as interface names, instead of interface
IP addresses. It will allow IPv6 operations. IP addresses. It will allow IPv6 operations.
