       The  Internet  Software  Consortium DHCP Client, dhclient,
       provides a means  for  configuring  one  or  more  network
       interfaces  using the Dynamic Host Configuration Protocol,
       BOOTP protocol, or if these protocols fail, by  statically
       assigning an address.

       The  DHCP  protocol  allows  a  host  to contact a central
       server which maintains a list of IP addresses which may be
       assigned  on  one  or  more  subnets.    A DHCP client may
       request an address from this pool, and then use  it  on  a
       temporary  basis  for communication on network.   The DHCP
       protocol also provides a mechanism whereby  a  client  can
       learn  important  details about the network to which it is
       attached, such as the location of a  default  router,  the
       location of a name server, and so on.

       On  startup, dhclient reads the _d_h_c_l_i_e_n_t_._c_o_n_f for configu
