Actually, it is all variants (.A - .D).  And more
specifically, it iterates through all the host IP

127.0.0.1
10.
172.16 - 172.31 (inclusive)
192.168.
169.254

Then, using this address it creates a random address
(sometimes changing all octets, sometimes just the
last three, and sometimes just the last two).
