Is this an accurate statement (pertaining to a Linux DHCP server
presiding over [mostly] MS PCs)?
 
"Having a system with a static IP assignment that is inside the range
of IPaddress' used by a DHC P server is not acceptable.  Reason being:
 If a new computer comes on-line, it may be issued that particular
IPaddress, and if so, there will be a problem.  This may never happen
on a small network. If there are only a handful of computers on the
network (half a dozen or so), you may never run into this sort of
problem.  BUT, if and when the network grows and gets to be fifty or a
 hundred strong, sooner or later, this problem will rear it's ugly
head.  A computer will come on-line and be issued an IP address that
has been set as a static address to another computer, .. . and then,
later on, that other computer with the static IP address will come
on-line, and at that point they will both compete for access that only
one can have. During the competition neither of them will get any
access and only when one gives up will the other gain any bandwidth or
access to any outside networks. Fixed IPs should _only_ be assigned to
IP address that are outside the range used by the DHCP server."
