  This is a VERY BAD IDEA.  They don't understand what they're doing.

  They obviously intend to use a private range of IP addresses.
Unfortunately, the story that all 192.x.x.x addresses are private is an old
wives' tale; the actual private ranges are spelled out in RFC 1918.
Specifically, the 192.36.x.x range is PUBLIC, and not theirs to allocate if
they ever intend to connect their company network to the Internet.
  Whether devices at these addresses see each other as local, or require a
router, will depend on the subnet mask selected -- without that information,
the question cannot be answered.

  If the company is big enough to have *departments* and assign them
different addresses, they're big enough to hire a knowledgable network admin
to set that up for them.  I recommend that they require at least CCNA
certification for this position, although Network+ might be sufficient.

  (Win2K server versions include DHCP server capability, and it can be a
great time-saver even if addresses are assigned statically.  Their intention
to set manual addresses *instead of* using DHCP sounds, to me, like seizing
on a solution instead of (or before) defining the *problem*.)
