In IPv4, the multicast address is 239.255.255.250 [5] and SSDP over IPv6 uses the address set ff0x::c for all scope ranges indicated by x. [6] This results in the following well-known practical multicast addresses for SSDP: 239.255.255.250 (IPv4 site-local address) ff02::c (IPv6 link-local) ff05::c (IPv6 site-local)
It operates over TCP and UDP port 3702 and uses IP multicast address 239.255.255.250 or ff02::c. As the name suggests, the actual communication between nodes is done using web services standards, notably SOAP-over-UDP. Various components in Microsoft's Windows Vista operating system use WS-Discovery, e.g. "People near me".
In support of link-local multicasts which do not use IGMP, any IPv4 multicast address that falls within the *.0.0.0 / 24 and *.128.0.0 / 24 ranges will be broadcast to all ports on many Ethernet switches, even if IGMP snooping is enabled, so addresses within these ranges should be avoided on Ethernet networks where the functionality of IGMP ...
A discover request is sent via HTTP and port 1900 to the IPv4 multicast address 239.255.255.250 (for the IPv6 addresses see the Simple Service Discovery Protocol (SSDP)): M-SEARCH * HTTP/1.1 HOST: 239.255.255.250:1900 MAN: "ssdp:discover" MX: 2 ST: urn:schemas-upnp-org:device:InternetGatewayDevice:1
