IPV6 security question (from textbook).

Hi,
I am taking an ecommerce security course and have found this site really helpful (especially since i am not exclusively a linux user).
The following question appears at the end of a chapter on PC and Server security.

Worms like Code Red scanned most of the entire IP address space looking for vulnerable computers to infect. How will the advent of IPv6 and it's huge address space affect the ability of a worm to propogate itself?

does anyone have any thoughts on this ?

Because the probability to find a live system among all the adress space is much lower.
Until they find new tricks.

True i just found this fact.

IPv6 is intended to provide more addresses for networked devices. IPv4 supports 4.3×109 (4.3 billion) addresses, which is inadequate to give one (or more if they possess more than one device) to every living person. IPv6 supports 3.4×1038 addresses, or 5×1028(50 octillion) for each of the roughly 6.5 billion people alive today.
