resolve.conf sortlist

[Steve Freed]

Same results using ping.

Someone else hinted that what might be happening is that the sortlist is
appened to the end of the default sort list, which in this case would be
10/8, which would have not have any effect since everthing is already
"sorted" in respects to the 10/8 network. The question is, do the
resolver routines use the natural netmask for the default sort list, or
does it use the netmask specified when when configuring the interfaces.
(which is 255.255.255.0 in our case)

On the other hand, I'm not quite buying this theory. The reason is, I
changed the sortlist to "166.63.0.0" and tried pinging
cwusa-mciworldcom.Atlanta.cw.net. and sometimes it gets the 166.48.48.98
and other times it gets the 166.63.134.10 address.
