There's a misunderstanding in force here.
Getting more IP addresses is (relatively) easy. nsict.org has a class
C uniquely allocated to it, which it is using internally on econet and
ethernet.
What's more difficult is arranging for your addresses to be routed to.
Demon's infrastructure only allows addresses within its class B
network to be dynamically routed between the PoPs as and when people
log on. It can dynamically route independent address sets to different
modem ports on a PoP, but no longer uses that facility. Users with
class C routeing invariably either have a leased line, or at least a
reserved modem on a specific PoP.
I suspect it is this routeing that Demon is refusing to do.
As people have already pointed out, for IP traffic that will never
leave your site, there are a bunch of reserved addresses that any
organisation can use internally. Pick some of these for your virtual
interfaces and such.
