Hmm, the line above definitely looks fishy, as it repeats localhost
twice with a separate entry "resnet.oberlin.edu", but if it were
"localhost.resnet.oberlin.edu", there would be nothing wrong with the
line (Having it won't help any but won't hurt, either).  But either
way, I don't think it should cause any serious problem.

Should be OK, but netmask being 255.255.0.0 means the entire class-B
network is not divided into subnets.  That is rather unusual, I think.
But other than that, it looks OK, and there's nothing *technically*
wrong with using a non-subnetted class-B network.

He says "when it detects the card", so it looks similar to the problem
discussed in the FAQ:
http://www.netbsd.org/Ports/mac68k/faq/faq-10.html#ss10.16

Or perhaps:
http://www.netbsd.org/Ports/mac68k/faq/faq-10.html#ss10.15

(but does the kernel panic?)

Anyway, if it's just during bootstrap, I wouldn't worry too much.

If his network really is not divided into multiple subnets, any
broadcast packet from any host on the network has to be received by
his Mac, and theoretically, there could be as many as 65534 hosts on
the network... ;-)
