Ip spoofing is a technique used to gain unauthorized access to computers, whereby the intruder sends messages to a computer with an IP address indicating that the message is coming from a trusted host. To engage in IP spoofing, a hacker must first use a variety of techniques to find an IP address of a trusted host and then modify the packet headers so that it appears that the packets are coming from that host.

Regarding broadcast, the packet is sent to all the hosts on the network once.

Whereas in flooding, the packets are sent multiple times.

As an example if we use a sendto() call to the intended IP's on the network we have only once, we could say it is a broadcast.

Whereas if we use the same call iteratively then it is flooding

Flooding and Broadcast are two routing algorithms used in computer networks today. Flooding sends all incoming packets through every outgoing edge. Broadcasting means every device in the network will receive a packet.
