we've got a 'mini commercial' cluster from our isp
which included our own subnet of 8 ip addresses
(with ...0 and ...7 being used for listen and
broadcast).
so yes, the netmask is supposed to be (binary)
11111111.11111111.11111111.11111000
(decimal)
255.255.255.248
where class C subnets are normally (binary)
11111111.11111111.11111111.00000000
(decimal)
255.255.255.0
we've got a windon't box that's got the same
subnet mask (255.255.255.248) and [unfortunately
:)] it works without a snag.
but apparently the netmask CAN be just about
anything you choose, for your private in-house
nets... it's just easier to maintain if you
keep all the zeroes together at the right
end of the binary string. at least that's
what i've read--
but next time i'm at the office, i could
experiment with trying a different netmask
if y'all think it would really help...

DEBIAN NEWBIE TIP #62 from Will Trillich <will@serensoft.com>
:
Wouldn't it be nice to SEE YOUR TABS WHILE YOU EDIT? With Vim,
you can do this with
:set listchars=tab:+-,trail:$
:set list
and format them via ":highlight NonText ...". (See ":help listchars"
and ":help highlight" for more info.) Put them in your ~/.vimrc if
you decide you like that setup.
