Scanning the broadcast of packets

If you encounter the issue of detecting a network broadcast, this recipe is for you. We can learn how to find the information from the broadcast packets.

How to do it...

We can use Scapy to sniff the packets arriving to a network interface. After each packet is captured, they can be processed by a callback function to get the useful information from it.

Listing 8.7 gives the code for scanning the broadcast of packets, as follows:
