DHCP Starvation and Block Ransomware DNS

[#1]

Hi,

Newbie here.

I want to do some tests on Infoblox

1. DHCP Starvation
I'll attack Infoblox with so many DHCP request, so 1 subnet ip will be full instantly

2. DNS Block Ransomware sites

user pc dns will point to infoblox

QUESTIONS:

1. How to setup Infoblox to block DHCP starvation

2. How to setup Infoblox to block Ransomware sites

any example of ransoware sites?

tq
