It could well be our "fault". We've been shipping Ethernet TCP/IP products for all kinds of platforms since 1983(ish) with a "default" IP address of 89 plus the bottom 3 bytes of the Ethernet address. I believe early versions of Berkeley (and possibly current versions) can also derive their IP address in this manner. For those familiar with our stuff, our default TCP startup scripts all have "netload" command lines containing the flag "-h 89.0.0.0". The TCP code this downloads to our various cards will then use the network number specified (89 in the default case) and replace the zero's in the host portion with bytes from the lower end of the Ethernet address. Incidentally, Callan were an early OEM of ours so that's us too! Now I think about it, SGI were also.

Then why has TWG's documentation had net 89 as the example net for many years (at least five now)? Also, they were using net 89 as their internal net up until about a year and a half ago. Just curious. -- Warner Losh imp@Solbourne.COM
