Yersinia, ettercap, and others have supported this for years, but crashing routers has always been easy.

An interesting application of dhcp flooding might be exhausting the ip space and knock a (dhcp'd) privleged host offline to get its ip.

As an IT graduate who has cursory knowledge in internet protocols and workings, what is this tool used for?

if you're asking the benefits of such a tool, one is actually in the readme:

For example, if a server quickly releases allocations that it doesn't receive responses from, the attack will be less effective.

So knowing that enabling dhcp makes you vulnerable in the respects that you only have a limited number of ips, we can modify our ip lease times to be shorter, and then test against the changes with the tool to see if its an acceptable remedy.
