Bogus question. First I'd say that these days, using the term "IP
protocol" still refers to IPv4, not IPv6 or both v4 and v6. Second, I
can configure all six addresses on my local machine and still access
the internet through a 7th IP.
a and e are RFC1918 private address space addresses so they should not
be used on the internet (an IP address ending in 0 can easily be valid
with a given netmask (say 255.255.0.0 in the case of e)). b is, like
you already pointed out, IPv4 multicast.
Where did you find this quiz ? It's total rubbish if you ask me.
Cheers,
Paul 'WEiRD' de Weerd
