I'd like to see some acknowledgement that there are legitimate uses of number resources that don't include "the public Internet".
It's already there in RFC 2050: 3 a) the organization has no intention of connecting to the Internet-either now or in the future-but it still requires a globally unique IP address. The organization should consider using reserved addresses from RFC1918. If it is determined this is not possible, they can be issued unique (if not Internet routable) IP addresses.
Does this concern make sense?
No.
Is there a(nother) better venue than the IAB?
ARIN, RIPE, APNIC, LACNIC, AfriNIC, NRO My company is one of several companies that operate IP networks that are not part of the public Internet but which do use globally unique registered IP addresses. --Michael Dillon
