Question about Multicast

[yigitemres]

Is there any multicast (ssdp) support like following example?

M-SEARCH * HTTP/1.1
HOST: 239.255.255.250:1900
MAN: "ssdp:discover"
ST: ssdp:all

I don't know what that means, so I presume "no."

I update my original post in order to be more clear what I mean by multicast.
