well i'm going to assume that we only use DHCP on the intranet for NAT,
10.0.0.x ip scheme. as for the router i think it's a static ip set in
the router and not DHCP'd. but i'm not positive, it makes sense that it
wouldn't be DHCP'd though.

<tip author="chris parker" type="organization">
Are you lazy and usually unorganized? Does your desk look like mine does
having 50 different papers strewn all around with one sentence that
serves as a reminder? Do you also lack charm and social skills and are
generally unhygenic?

Well I can't help you on the last question, but I can give some
suggestions as to the other ones. I've come to take advantage of a small
pad of paper, pen, and my outlook Tasks list. Any task list organizer
will do, just make sure you write down what you need to do and at the
end of the day anything that is not done should be entered into your
Tasks list with, if possible, a priority setting.

was that weak? oh man i'm bad at this. ;)
