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)
A multicast address is a logical identifier for a group of hosts in a computer network that are available to process ... 239.255.255.250 Simple Service Discovery ...
Web Services Dynamic Discovery (WS-Discovery) is a technical specification that defines a multicast discovery protocol to locate services on a local network. It operates over TCP and UDP port 3702 and uses IP multicast address 239.255.255.250 or ff02::c.
It operates over TCP and UDP port 3702 and uses IP multicast address 239.255.255.250. As the name suggests, the actual communication between nodes is done using web services standards, notably SOAP-over-UDP. Windows supports it in the form of Web Services for Devices and Devices Profile for Web Services. Many devices, such as HP and Brother ...
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
Sent by multicast routers to determine which multicast addresses are of interest to systems attached to the network(s) they serve to refresh the group membership state for all systems on its network. Group-specific membership queries Used for determining the reception state for a particular multicast address. Group-and-source-specific queries
The Ethernet frame used in LLDP typically has its destination MAC address set to a special multicast address that 802.1D-compliant bridges do not forward. Other multicast and unicast destination addresses are permitted. The EtherType field is set to 0x88cc. Each LLDP frame starts with the following mandatory TLVs: Chassis ID, Port ID, and Time ...
IPv6 addresses are assigned to organizations in much larger blocks as compared to IPv4 address assignments—the recommended allocation is a / 48 block which contains 2 80 addresses, being 2 48 or about 2.8 × 10 14 times larger than the entire IPv4 address space of 2 32 addresses and about 7.2 × 10 16 times larger than the / 8 blocks of IPv4 ...
