These scripts can find different devices and services on a local network, such as printers, servers, and routers. Each script has a specific function, like discovering DHCP servers or identifying devices that support certain protocols. Overall, these tools help users gather information about their network environment efficiently. ## Highlights For a description of this category, see [broadcast NSE category in the Nmap documentation](https://nmap.org/book/nse-usage.html#nse-category-broadcast).

By default, the script uses a static MAC address (DE:AD:CO:DE:CA:FE) in order to prevent IP pool exhaustion. [broadcast-dhcp6-discover](https://nmap.org/nsedoc/categories/broadcast.html/../scripts/broadcast-dhcp6-discover.html) Sends a DHCPv6 request (Solicit) to the DHCPv6 multicast address, parses the response, then extracts and prints the address along with any options returned by the server.
