Which scanning technique relies on the Simple Service Discovery Protocol (SSDP) to interact with devices using multicast addresses?

• A. DNS Enumeration
• B. SNMP Enumeration
• C. SSDP Scanning
• D. SMTP Banner Grabbing

Answer: (C)

SSDP-based device discovery relies on multicast communications. This scanning technique sends discovery messages using the Simple Service Discovery Protocol to the IPv4 multicast address 239.255.255.250 (port 1900). UPnP-enabled devices listening on that multicast group respond with their service information, allowing you to map devices and their capabilities across the local network. This multicast interaction is what distinguishes it from other enumeration methods, which target specific services or use unicast queries (DNS enumeration queries DNS records, SNMP enumeration queries MIB data, and SMTP banner grabbing reads the banner from mail servers over TCP).
