<DIV><FONT face=Arial size=2><SPAN class=312091613-14052002>There are a limited
number or organisations that for legitimate reasons require globally unique
address space apart from rfc1918 private address space, but may not
connect to or announce these prefixes on the Internet. Rfc 2050 referenced such
situations as seen in the extract below.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=312091613-14052002>On a case by case
basis, it may be appropriate for these few organisations to become LIRs. Perhaps
the IPv4 Address Allocation policy should reference such circumstances as rfc
2050 did?</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2>Assignment Framework</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2> An assignment is the delegation of
authority over a block of IP<BR> addresses to an end
enterprise. The end enterprise will use<BR> addresses
from an assignment internally only; it will not sub-<BR> delegate
those addresses. This section discusses some of the issues<BR>
involved in assignments and the framework behind the assignment
of<BR> addresses.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2> In order for the Internet to scale
using existing technologies, use<BR> of regional registry services
should be limited to the assignment of<BR> IP addresses for
organizations meeting one or more of the following<BR>
conditions:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2><STRONG> a) the
organization has no intention of connecting
to<BR> the Internet-either
now or in the future-but it
still<BR> requires a
globally unique IP address. The
organization<BR> should
consider using reserved addresses from
RFC1918.<BR> If it is
determined this is not possible, they can
be<BR> issued unique (if
not Internet routable) IP addresses.</STRONG></FONT></DIV></BODY></HTML>
