Hmm... Interesting. Someone else was asking me how to do this today,
and we noticed that in Windows (at least WinXP), entries that are
exclusively in the hosts file aren't resolved if "Enable concurrent DNS
requests" is enabled.
I'm assuming this is because ADNS isn't following the Windows host
resolution order, it simply makes calls to DNS and ignores hosts,
lmhosts, WINS, etc.
I just hadn't noticed that before - am I correct? If so, it's a bit of
a gotcha that might make sense to add as an entry in the FAQ (or better
yet, in the upcoming Wiki documentation =)
The situation also reminds me of a couple of things I wanted to discuss:
Topic #1:
Periodically (though rarely) I DO want to do some network-level name
resolution. However, I almost NEVER look at traffic from systems
within my own network, so DNS resolution is pretty useless to me. I
usually want to just add some entries to my host file to force names to
appear in the Dest/Source columns in the packet list. On unix-like
systems I can then go edit search order or something to only look at
"hosts", but otherwise opening a trace can be very, very (very!) slow.
On Windows I don't really have this option anyway.
Is there a better way to force only name resolution resolution from a
certain source? Would it be difficult and/or a good idea to add a
feature that allows forced mapping of addresses to certain names WITHIN
Ethereal?
Topic #2:
I've noticed that in some cases when MAC name resolution is turned on,
the address is resolved into an IP address instead of OID+bytes. I
haven't sat down to try to figure out when this happens - I'm assuming
Ethereal is doing some ARP inspection or something like that. I almost
NEVER want to see MAC addresses resolved into a name, I'd rather always
see an attempted OID resolution.
It would be great if either 1) This behavior could be disabled, or 2)
The IP address is displayed in ADDITION to the resolved MAC "name". Do
others agree? I prefer #2 since it seems a bit more intuitive and I
hate adding unnecessary preferences, but perhaps I'm forgetting
something.

Put them in your hosts file like this:
156.8.234.5 banana
156.124.54.56 green
Exactly what name the file has depends on your O/S
