As a result, there are no doubt many network islands running with net #89 (or 49, but that is a different though similar story). Some time ago, in a fit of embarrassment and remorse, I registered a class-C network for SGI to serve exactly this purpose. At that time, I petitioned the Gods for an official solution. In Their wisdom, though no doubt not because of my unworthy request, They declared that host 192.0.2.1 on the official test network should be used. Since then, it has become fairly elaborate. An IRIS comes named '192.0.2.1 IRIS' on its disks, tapes, and even in NVRAM. When the PROM's, bootp (RFC-951) server, and various "system administration" tools notice the bogus number, they complain or do something else reasonable sounding. If I misunderstood the Gods, I hope that someone will enlighten me. Vernon Schryver Silicon Graphics vjs@sgi.com
