What you do is go to your LIR and ask for a /24 and tell them "I am going to use this for <purpose> which is at best semi-internal". It has worked for me; I got a PI /24 for the facility management system in a datacenter. (MODBUS over IP stuff, windows machines and embedded boxes sending email alarms about burning UPSes and sauna-hot computer rooms) My colleagues argued that "this network won't ever be connected to anything" but it took all of one week before they were proved wrong and the first contractor VPN box was installed. QED. The really, really, nice thing with registered PI or PA space is that it is pretty unique, bar fatfingering and route hijacking. Once there is a merger, the company with a RIPE db entry for the nonrouted space will have a most convincing position in merger negotiations: "This is our space: _you_ will renumber." Burning v4 space is good. Gets us v6 faster. -- Måns Nilsson M A C H I N A HUGH BEAUMONT died in 1982!!
