On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
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".
