One of the points of NAT is to make renumbering easy. Silly them.
I have a rule: Your network, your rules. If they want to be
disconnected from Africa, you can't stop them. And they are not
"hijacking" the /8, it is not announced on the 'Net. This is
identical to a null route inside their ASN. I would never dream of
telling them they cannot decide which netblocks should be routeable
inside their own ASN.
Fortunately, I have another rule: My network, my rules. If someone
can find the real addresses for FastWeb uses for the NAT pool and
post it here (and other *NOG lists), networks can ensure that
FastWeb's end users will be unable to communicate with a lot more
than "a few African networks". I think the show of solidarity would
be good for the 'Net.
