I found a statement on http://en.wikipedia.org/wiki/AMPRNet that says:
44.128.0.0/16[edithttp://en.wikipedia.org/w/index.php?title=AMPRNet&action=edit§ion=2 ]
*44.128.x.x* is the testing subnet and consists of 65,536 (216) addresses. Much akin to 10.0.0.0/8, 172.16.0.0/12, 169.254.0.0/16 or 192.168.0.0/16, this is an unroutable private IP blockhttp://en.wikipedia.org/wiki/Private_network. Connectivity to the rest of the network should be given through router gateways http://en.wikipedia.org/wiki/Gateway_(telecommunications) much as one would do with Network address translationhttp://en.wikipedia.org/wiki/Network_address_translation in any other private IP block.
Is this truly the case? When I look at the portal, this /16 would be towards the end of the US allocations, and just before the Japan allocations.
If this is not true, do we have a Private block in the 44/8 for use that is not routable?
